-
- Jeff Prosise 1988/No. 2 (Utilities)
-
-
- Purpose: Edits or creates custom help or reference screens that can be
- popped up over an application program or at the DOS prompt with the HELP.COM
- (PC Lab Notes, 1988/No. 1). Also provides full control of character and
- video attribute bytes and permits insertion of single-line, double-line, or
- pattern characters from the extended-ASCII PC text-graphics set.
-
- Format: PAINT [filespec]
-
- Remarks: The optional filespec is the filename (plus drive and path, if
- needed) of a help/reference screen previously saved for HELP.COM by means of
- the related CAPTURE program (PC Lab Notes, 1988/No. 1). If filespec is
- omitted, PAINT permits creating and saving a new screen in the appropriate
- format. HELP files are 4,000-byte screen buffer images, and as many as 14
- may be chained together for successive display. The PgUp and PgDn keys in
- PAINT move through multiple-screen files.
-
- The Ins key toggles the PAINT editor between overstrike (the default)
- and insert modes. The Del key deletes the character under the cursor and
- closes up the text. In overstrike mode, the Backspace key moves the cursor
- left without moving any text characters to its right. In insert mode, the
- Backspace drags characters with it. The cursor can be moved anywhere within
- the viewing area by means of the cursor keys. Home and End move the cursor
- to the ends of the text line, and Enter performs the usual carriage
- return/line feed.
-
- Function key F1 lists the menus presented by each function key, and
- Esc de-selects any active menu. F3 toggles between text-only and text-plus
- -attribute modes, which are also reflected in the operation of the Backspace
- and Del keys. Attributes are selected by number(s) after pressing F2, which
- presents 16 foreground and 8 background color choices (color systems) or
- normal, reverse, boldface, or underline (monochrome systems). By positioning
- the cursor on any displayed character and pressing F2 twice, that video
- attribute can be selected without using the menu numbers. Pressing Enter
- defaults to the current selection. Selected attributes remain in effect
- until changed.
-
- Small or irregular screen areas can be "painted" with the current
- attribute by holding down the Ctrl key and pressing the desired cursor Arrow
- keys. Large screen areas may be defined by locating the cursor at one corner
- and pressing F5, then moving to the diagonal corner and pressing F5 again. A
- menu choice is then presented, either to clear the defined block of text
- characters or to paint them all with the current video attribute. Pressing
- F5 twice without moving the cursor defines the entire screen and presents the
- same choice.
-
- Function key F4 permits selection of single-line, double-line,
- patterns, or asterisks that are then written to the screen by holding down the
- Alt key and pressing the cursor arrows. Where lines cross, appropriate
- junction symbols are substituted. F6 asks for a filename under which the file
- is to be saved (it supplies the original filename as a default) and saves the
- file. Compensation is automatically applied to adjust for differences in
- display size. Pressing F7 returns to DOS.

-
- Notes:
-
- 1. While PAINT is intended primarily for use with screens that use the
- HELP program, it can be used to advantage in prototyping screens for
- application programs and in the design layout of other pop-up windows.
-
- 2. PAINT is compatible both with traditional PCs and with the new PS/2 line.
