\fBDescription
.sp
.in 0.4i
This enhanced version of @\.\.\.PROMPT requires the inclusion of
the header file FTMENUTO\.CH in any source file that uses it\.
It is compatible with, and may be used in place of, the standard
Clipper @\.\.\.PROMPT command\.
.sp
Clipper\'s @\.\.\.PROMPT and MENU TO commands are fine as far as
they go\.  But many times you need more flexibility\.  As
you\'ll no doubt notice if you read the argument list, this
function is almost completely flexible\. You can adjust
locations and colors for every part of the prompt and its
associated message\.  In addition, since you can control the
effect of the arrow keys, you can allow both horizontal and
vertical movement, or even disable certain arrow keys if you
so desire\.
.sp
Note that this command can also be called using function-style
syntax\.  See the entry for FT_PROMPT() for further details\.
.sp
Also note that this command calls an internal routine called
__FTPROMPT()\. __FTPROMPT() was written in assembler\.  Check
the file TMENU\.ASM if you\'re interested in seeing the
assembler source code\.
.sp
All the examples below use the command version\.  If you\'re
interested in seeing the function version, compile the
examples with the /P switch and then examine the resulting
\.PPO file\.

.sp
.in 0.4i
the number of the selected option, or 0 if [Esc] is pressed\.
.sp
.in 0.08i
\fBDescription
.sp
.in 0.4i
FT_Ach2tb() is a greatly enhanced, fully featured replacement for
Achoice(), based on a Tbrowse object\.  Each element of <aArray> needs
to be composed as follows:
.sp
.in 0.72i
.ta 0.72i 1.2i 2.24i
Option    ,    Message    , HotKeyPos, HotKeyColor, Selectable
.br
.ta
.in 0.4i
.ta 3.04i 3.44i 3.76i 4.48i 4.88i 5.52i
{ "Utilities","System Utilities",    3    ,    "+gr/b"    ,    \.T\.    }
.br
.ta
.sp
All elements except for the first, the option itself, are optional\.
IF \'Message\' is NIL, no message is displayed\.  \'HotKeyPos\' is the
position within \'Option\' of the hotkey\.  In the example above, the
hotkey for \'Utilities\' is the first \'i\', i\.e\., at position 3\.  The
default is 1\.  \'HotKeyColor\' is the color to use for the hotkey
.ta 2.72i
display\.  The default is hiwhite    on the current background color\.
.br
.ta
\'Selectable\' is a logical indicating whether or not that option can
be selected\.  The default is \.T\.
.sp
The A_CHOICE() UDC in FT_ACH2T\.CH makes using FT_ACH2TB() a breeze\.
The myriad of parameters can be written in any order\.  Only <nToprow>,
<nTopcol>, and <aArray> are required\.  See the example below\.
.sp
There may be some confusion over \'unselected\' and \'unselectable\'
options\.  The former refers to any option not currently covered
by the selection bar\.  The latter refers to options you have
designated unselectable in subelement 5 of <aArray>, i\.e\., by
writing \.F\.
.sp
To enable tagging, pass any ASCII character as <cTagchar>\.  To
tag/untag all options, press [SPACE]\.  To tag/untag individual
options, press [+] and [-] respectively\.  To test for the tagged
status of an option, use the WAS_TAGGED() UDC in FT_ACH2T\.CH\. To
check the entire array for tags, use Aeval() in conjunction with
Was_Tagged() as in the example below\.  When tagging is enabled, the
string "Tags" will be written across the bottom row of the box in
hiwhite on the current background color\.
.sp
Because FT_ACH2TB() takes over the [SPACE], [+], and [-] keys, it saves
any SET KEY procedures you might have set them to, and restores same
on returning\.  Any other procedures you might have SET KEYs to will
fly when FT_ACH2TB() is called\.\.\.thanks to the INKEY() replacement,
SKINKEY()\.
.sp
The piece de resistance of FT_ACH2TB() is its ability to execute
a user function designed entirely by you\.  It is called after each
keypress, and because it is completely open-ended, extends the
the reach of FT_ACH2TB() to the limits of Clipper\.  See the docu-
mentation under <bUserfunc> above\.

A couple of notes about the adder:
.sp
.sp
1\.) It was designed to be used on an Enhanced keyboard with
.in 0.8i
separate <DELETE> key\. <DELETE> is used to clear the adder\.
However, it will still work on a Standard keyboard\.
.sp
.in 0.48i
2\.) It uses the <SPACE> bar to shift from Add/Subtract
.in 0.8i
mode to Multiply/Divide\. That means the <+> and <-> keys
become the <*> and </> keys\.
.sp
.in 0.48i
3\.) You do not have to display the tape\. You may turn it on
.in 0.8i
at any time by pressing <T>\. You may SCROLL back through
the tape once there are more than 16 entries in the
adder, by pressing <S>\.
.sp
.in 0.48i
4\.) To Quit the Adder just press <ESC>\. To return your Total
.in 0.8i
to the application press <F10>\. The adder will place the
Total in the active GET variable using oGet:VarPut()\. The
adder will only return a Total to a numerical GET!
.sp
.in 0.48i
5\.) There are many support functions that you might find
.in 0.8i
interesting\. They are part of my personal library, but
are necessary to the operation of the adder\.
You might want to pull these out to reduce the overall
size of the adder\. Many are worth at least a little
time studying\.
.sp
.in 0.48i
6\.) To make FT_Adder a Hot key from inside your application
.in 0.8i
at the beginning of your application add the line:
.sp
.in 1.36i
.ta 1.36i
SET KEY K_ALT_A    TO FT_Adder
.br
.ta
.sp
.in 0.8i
This will make <ALT-A> a key "Hot" and permit you to
Pop - Up the adder from anywhere in the application\.
.sp
.in 0.48i
7\.) If you use the UDF replacement for INKEY() that Don Caton
.in 0.8i
posted on Nanforum (see FT_SINKEY()), you can even have
active hotkeys in an INKEY()\.

\fBArguments
.sp
.in 0.4i
\fB<aMessageArray>\fR is a multidimensional array of messages to be
displayed and the color attributes for each message\.
.sp
The first dimension of the array contains one or more elements,
each representing one line in the message box, up to the maximum
number of rows on the screen\.
.sp
The second dimension of the array contains a color attribute for
the corresponding element in dimension one, plus one additional
element for the color of the box border\.  Dimension two will
always contain one more element than dimension one\.  If an
attribute is omitted, the last color selected will be used\.
.sp
\fB<Key2Check>\fR is a character string of one or more keys to check
for\.  If omitted, the message is displayed and control is returned
to the calling procedure\.  If one character is specified,
FT_DISPMSG() waits for one keypress, restores the screen and
returns\.  If multiple characters are specified, FT_DISPMSG()
remains in a loop until one of the specified keys has been
pressed, then restores the screen and returns\.
.sp
\fB<nTopBoxRow>\fR is the upper row for the message box\.  If omitted, the
box is centered vertically\.
.sp
\fB<nLeftBoxColumn>\fR is the leftmost column for the box\.  If omitted, the
box is centered horizontally\.
.sp
\fB<cBoxType>\fR is a string of characters or a variable for the box
border\.  See the @\.\.\.BOX command\.  If omitted, a double box is
drawn\.
.sp
\fB<lShadow>\fR is a logical variable\.  If true (\.T\.) or omitted, it
uses FT_SHADOW() to add a transparent shadow to the box\.  If
false (\.F\.), the box is drawn without the shadow\.
.sp
.in 0.08i
\fBReturns
.sp
.in 0.4i
If <Key2Check> is not specified, FT_DISPMSG() will return false
(\.F\.)\.
.sp
If <Key2Check> is a one-character string, FT_DISPMSG() will return
true (\.T\.) if the user presses that key, or false (\.F\.) if any
other key is pressed\.
.sp
If <Key2Check> consists of multiple characters, it will lock the
user in a loop until one of those keys are pressed and return the
INKEY() value of the keypress\.
.sp
.in 0.08i
\fBDescription
.sp
.in 0.4i
FT_DISPMSG() is a multi-purpose pop-up for user messages\.
Multiple lines may be displayed, each with a different attribute\.
The box will be automatically centered on the screen, or the row
and/or column can be specified by the programmer\.  It also centers
each line of the message within the box\.

This function greatly simplifies the process of displaying light-bar

length, a box is drawn around the prompts, the box is automatically
centered on the screen, and the underlying screen is restored after
a menu selection has been made\.

.sp
.in 0.08i
\fBArguments
.sp
.in 0.4i
\fB<bVarNameBlock>\fR is a "get-set" code block which allows the
retrieval and assignment of the variable which will receive
the return value\.  Its initial value is used to determine the
initial active prompt\.
.sp
The code block must be in the form:
.sp
.in 0.64i
{|_1| IIF( _1 == NIL, \fB<var>\fR, \fB<var>\fR := _1 ) }
.sp
.in 0.4i
For example, if the variable to receive the return value is
named "nChoice", the code block would look like:
.sp
.in 0.64i
{|_1| IIF( _1 == NIL, nChoice, nChoice := _1 ) }
.sp
.in 0.4i
Although it is good practice to always declare your variables,
the variable to receive the return value does not need to exist
before calling FT_MENUTO()\.  If it does exist and is a numeric,
its value will be used to determine the initial prompt\.  If it
does not exist, the initial prompt will default to the first one\.
.sp
If you use this function by way of the MENU TO command along with
the FTMENUTO\.CH header file, this code block will automatically
be created for you by the preprocessor\.
.sp
\fB<cVarName>\fR is the name of the memvar to which the menu
choice is returned\.
.sp
\fB<lNoSnow>\fR is optional and specifies whether or not to
implement snow-suppression on CGA monitors\.  The default is
\.F\., meaning that no snow-suppression will occur\.  This
option is only meaningful for CGA displays\.
.sp
\fB<lKeep>\fR is optional and indicates whether or not to destroy
the prompt list once the menu has been executed\.  If \.T\.,
then the prompts will be kept, allowing the menu to be
executed multiple times without redefining the prompts\.  The
default is \.F\., meaning the prompts will be destroyed once
the menu has executed\.
.sp
\fB<lCold>\fR is optional and controls the operation of the
hotkeys\.  If \.T\., then pressing a hotkey will not result in
a menu selection\.  Instead, it merely changes the active
prompt\.  This allows more than one prompt to have the same
hotkey\.  The default is \.F\., meaning the hotkeys will
function the same way they do in Clipper\.
.sp
.in 0.08i
\fBReturns
.sp
.in 0.4i
A numeric value representing the menu choice selected, or zero
if the ESC key was used to exit the menu\.
.sp
.in 0.08i
\fBDescription
.sp
.in 0.4i
This function is a replacement for Clipper\'s MENU TO
command\.  In fact, you may wish to consult TMENU\.CH, which
contains a user-defined command that closely adheres to
standard Clipper syntax and makes this function infinitely
easier to use\.  I strongly recommend using the command
version because it is complementary to the associated
@\.\.\.PROMPT command\.
.sp
This function is very similar to the Clipper version\.  The
main differences are that you have more control over hotkey
operation, and you can keep the prompts alive after the menu
has executed, if you so desire\.  Please be aware that this
function does not qualify as a "wait state" and so do not
expect any wait state-associated activity to occur\.
Nevertheless, I have included support for any SET KEY
redirections through the magic of code blocks\.  A loop is
used to check to every possible INKEY() value to see if it
has been redirected\. This is necessary because Clipper
provides no way to check SET KEY status\.  If you\'re
interested in improving performance, alter the source code
to receive an array of keys that have been redirected, and
remove the previously mentioned loop\.  Using the loop does
make the routine a bit more generic, so it\'s a trade-off\.
Your call, do as you see fit\.
.sp
Note that this function calls an internal routine called
__FTMENUTO()\. __FTMENUTO() was written in assembler\.  Check
the file TMENU\.ASM if you\'re interested in seeing the
assembler source code\.
.sp
All the examples below use the command version\.  If you\'re
interested in seeing the function version, compile the
examples with the /P switch and then examine the resulting
\.PPO file\.

\fBDescription
.sp
.in 0.4i
A good way to display information messages during the running
of an application is to send them all to the SAME line on the
screen where users are expected to look for them\. In order to
give users a chance to read the current message before the next one
is displayed we may need to insert a delay after each message\.
.sp
FT_PENDING() function displays messages by keeping track of
the time of the last message and providing a delay ONLY if the next
pending message is issued much too soon after the current one\.
.sp
.sp
.in 0.08i
\fBExamples
.sp
.in 0.4i
.br
FT_PENDING("Message one",20,0,3,"W+/G") // Displays "Message one\."
.in 3.6i
.br
// sets row to 20, col to 0\.
.br
// wait to 3 and color to
.br
// bright white over green\.
.in 0.4i
.ta 2.24i
.br
FT_PENDING("Message two")    // Displays "Message two", after 5 sec\.
.br
.ta
.br
FT_PENDING("Message three") // Displays "Message three", after 5 sec\.
.sp
.sp
Note that default row, col, wait time and color need to be set only
once in the very first call to FT_PENDING() and only if the internal
default values are not appropriate\.

\fBDescription
.sp
.in 0.4i
This function is a replacement for Clipper\'s @\.\.\.PROMPT
command\.  In fact, you may wish to consult FTMENUTO\.CH, which
contains a user-defined command that closely adheres to
standard Clipper syntax and makes this function infinitely
easier to use\.  I strongly recommend using the command
version because the large number of possible arguments makes
the function version too prone to error\.
.sp
Clipper\'s @\.\.\.PROMPT and MENU TO commands are fine as far as
they go\.  But many times you need more flexibility\.  As
you\'ll no doubt notice if you read the argument list, this
function is almost completely flexible\. You can adjust
locations and colors for every part of the prompt and its
associated message\.  In addition, since you can control the
effect of the arrow keys, you can allow both horizontal and
vertical movement, or even disable certain arrow keys if you
so desire\.
.sp
Note that this function calls an internal routine called
__FTPROMPT()\. __FTPROMPT() was written in assembler\.  Check
the file TMENU\.ASM if you\'re interested in seeing the
assembler source code\.
.sp
All the examples below use the command version\.  If you\'re
interested in seeing the function version, compile the
examples with the /P switch and then examine the resulting

\fBArguments
.sp
.in 0.4i
\fB<cJustType>\fR is a character indicating the type of text justification\.
"L" or "l" will cause the text to be left-justified in the box\.
Centered text is the default\.
.sp
\fB<cRetWait>\fR is a character which determines if the function will wait
for a keypress after displaying the box\.  "W" or "w" will cause the
function to wait for a keypress before returning control to the
calling routine\.  Not waiting is the default
.sp
\fB<cBorType>\fR is a character which determines whether a single or double
border will be displayed\.  "D" or "d" will cause a double border to
be displayed\.  A single border is the default\.
.sp
\fB<cBorColor>\fR is a character string denoting the border color\.  \'N/W\' is
the default if this parameter is not a string\.
.sp
\fB<cBoxColor>\fR is a character string denoting the text color\.  \'W/N\' is
the default if this parameter is not a string\.
.sp
\fB<nStartRow>\fR is a number denoting the starting row\.  If \'99\' is passed,
the box is centered vertically\.  If necessary, nStartRow is decreased
so the entire box can be displayed\.
.sp
\fB<nStartCol>\fR is a number denoting the starting column\.  If \'99\' is passed,
the box is centered horizontally\.  If necessary, nStartCol is decreased
so the entire box can be displayed\.
.sp
\fB<cLine1>\fR thru \fB<cLine8>\fR are 1 to 8 character strings to be displayed\.
They are truncated to fit on the screen if necessary\.

FT_XBOX() allows the programmer to display a message box on the screen
without needing to calculate the dimensions of the box\.  Only the upper
left corner needs to be defined\.  The function will calculate the lower
right corner based on the number and length of strings passed\.
.sp
A maximum of eight strings can be displayed\.  If a string is too long
to fit on the screen it is truncated\.
.sp
The first seven parameters are optional\.  The default settings are:
.in 0.64i
Lines of text are centered\.
Control is returned to the calling routine immediately\.
A single line border is painted\.
The border is black on white\.
The text is white on black\.
The box is centered both vertically and horizontally\.

\fBArguments
.sp
.in 0.4i
\fB<var>\fR is the name of the variable to assign the result of the
menu selection\.
.sp
\fBNOSNOW\fR implements snow-suppression on CGA monitors\.  If not
specified, no snow-suppression will occur\.  This option is only
meaningful for CGA displays\.
.sp
\fBKEEP\fR causes the prompt list to be retained after the menu
has been executed, allowing the menu to be executed multiple
times without redefining the prompts\.  If not specified, the
prompts will be destroyed once the menu has executed\.
.sp
\fBCOLD\fR suppresses automatic menu termination when a prompt\'s
hotkey is pressed\.  If this clause is present, pressing
a prompt\'s hotkey will move the highlight to the proper menu
selection but will not terminate the menu\.  If not present,
pressing a hot key will terminate the menu, as it does in the
standard Clipper MENU TO command\.
.sp
.in 0.08i
\fBDescription
.sp
.in 0.4i
This enhanced version of MENU TO requires the inclusion of
the header file FTMENUTO\.CH in any source file that uses it\.
It is compatible with, and may be used in place of, the standard
Clipper MENU TO command\.
.sp
This command is very similar to the Clipper version\.  The
main differences are that you have more control over hotkey
operation, and you can keep the prompts alive after the menu
has executed, if you so desire\.  Please be aware that this
function does not qualify as a "wait state" and so do not
expect any wait state-associated activity to occur\.
Nevertheless, I have included support for any SET KEY
redirections through the magic of code blocks\.  A loop is
used to check to every possible INKEY() value to see if it
has been redirected\. This is necessary because Clipper
provides no way to check SET KEY status\.  If you\'re
interested in improving performance, alter the source code
to receive an array of keys that have been redirected, and
remove the previously mentioned loop\.  Using the loop does
make the routine a bit more generic, so it\'s a trade-off\.
Your call, do as you see fit\.
.sp
Note that this command can also be called using function-style
syntax\.  See the entry for FT_MENUTO() for further details\.
.sp
Also note that this command calls an internal routine called
__FTMENUTO()\. __FTMENUTO() was written in assembler\.  Check
the file TMENU\.ASM if you\'re interested in seeing the
assembler source code\.
