- GETKEY DOCumentation
- ________________________________________________________________
-
- GETKEY is used in batch files to get keys from the keyboard and
- exit with an ERRORLEVEL that can then be tested. A prompt line
- can be displayed. Any alphanumeric character can be a valid
- response but valid responses must be specified on the command
- line. An Enter exits with an ERRORLEVEL equal to the last valid
- response character on the command line. By using the /F command
- line option, all unshifted function keys become valid responses.
- Non-valid responses cause the bell to be sounded.
-
-
-
- Command line format:
-
- GETKEY [/F] "prompt" [xyz]
-
- where xyz are valid response characters. All characters are
- converted to uppercase so you do not have to worry about case
- conversion. The last character entered will be the default if
- Enter is pressed.
-
- The string between the quotes will be displayed as the prompt
- line.
-
- If the /F (or /f) option is used, F1 - F10 become valid
- responses.
-
- Return ERRORLEVELS
-
- Function keys return their extended code plus 100.
-
- F1 159 F2 160 F3 161 F4 162 F5 163 F6 164
- F7 165 F8 166 F9 167 F10 168
-
- Alphabetical characters "a - z" and "A - Z" are converted to
- ERRORLEVELS of 65 - 90 respectively.
-
- Remember that ERRORLEVELS must be tested from the highest to the
- lowest value. This is a DOS "feature".
-
- GETKEY entered with no command line parameters will cause the
- program to exit with an ERRORLEVEL of 0 and print:
-
- Useage: GETKEY [/F] "Prompt" [XYZ]',13,10,'$'
-
-
-
- Some Examples
-
- Here is a simple (minded) batch file do demo the use of GETKEY
- using the /F option. You can cut it out with and editor and
- execute it if you desire.
-
- MYMENU.BAT
-
- echo off
- :begin
- cls
- Echo.
- Echo.
- Echo MY MENU
- Echo.
- Echo F1 Directory
- Echo F2 Wide Directory
- Echo F3 Print Directory
- Echo F4 Save Dir to MYDIR
- Echo F5 Directory of A:
- Echo F6 CHKDSK
- Echo F7 Date
- Echo F8 Time
- Echo F9 DOS Version
- Echo F10 Exit to DOS
- Echo.
- GETKEY /F " Select: "
- if ERRORLEVEL==168 goto exit
- if ERRORLEVEL==167 goto version
- if ERRORLEVEL==166 goto time
- if ERRORLEVEL==165 goto date
- if ERRORLEVEL==164 goto chkdsk
- if ERRORLEVEL==163 goto dira
- if ERRORLEVEL==162 goto dirsave
- if ERRORLEVEL==161 goto printdir
- if ERRORLEVEL==160 goto dirwide
- if ERRORLEVEL==159 goto dir
- goto begin
-
- :dir
- echo.
- dir /p
- pause
- goto begin
-
- :dirwide
- echo.
- dir /w/p
- pause
- goto begin
-
- :printdir
- echo.
- dir > lpt1
- goto begin
-
- :dirsave
- echo.
- dir > mydir
- goto begin
-
- :dira
- echo.
- dir a: /p
- pause
- goto begin
-
- :chkdsk
- echo.
- chkdsk
- pause
- goto begin
-
- :date
- echo.
- date
- pause
- goto begin
-
- :time
- echo.
- time
- pause
- goto begin
-
- :version
- echo.
- ver
- pause
- goto begin
-
- :exit
- echo.
- Echo Have a nice day!
-
- If you don't use all of the funtion keys, test for the lowest
- value you DON'T want and do a "goto begin".
-
-
- Example 2
-
- Here is a very simple batch file to illustrate the valid options
- and the default enter. With this batch file, and Enter is the
- same as a Yes answer.
-
- DIRP.BAT
-
- Echo off
- CLS
- echo.
- echo.
- echo.
- GETKEY "Do you want a DIRectory? [Y/n] " ny
-
- if ERRORLEVEL==89 goto yes
- goto exit
-
- :yes
- echo.
- echo.
- dir /p
-
- :exit
-
- Note also that only the "Y" is tested for. The "N" is the only
- other option so it is not necessary to test for it.
