GEXT is a small utility to retrieve an extended key sequence.
GEXT will exit with an errorlevel or a selected environment
variable set to the scan code value.
Syntax : GEXT var /F
Where: 'var' is any valid DOS environment variable
'/F' associates extended keys with numbers of 1 thru 10
for function keys 1 thru 10, 11 thru 20 for
shifted function keys, 21 thru 30 for alt+function
and 31 thru 40 for ^function. Without the /F, all
extended keys are reported with the ascii values. If
other keys are pressed, they are ignored, except
for ^C or ESC, these return an errorlevel of 0FF hex
Defaults: NONE
ERRORLEVELS: 255 (0FF) = Program Problem (call Author)
254 = Abort via ^C or Escape
1 and up = Scan code of key or as per notes above
EXAMPLES:
GEXT
Returns an errorlevel for the scan code of the extended key.
GEXT KEY
Returns the scan code as an ascii character in variable KEY
GEXT /F
Extended codes are returned as errorlevel using special values as
defined in the section 'Where:' above.
** NOTE ** see your DOS manual for extended scan codes
For additional usage and information on using these utilities see
the file SEBFU.DOC or BATUT.DOC.
