The DO file processor supports the ability to specify the upper or lower case version of a $KBDn variable on the command line, which can be handy when building case-sensitive Unix commands from input strings. The following example makes this clear:
;TEST.CMD
:<Input something >
:K1
DOTEST $KBD1 LCS($KBD1) UCS($KBD1)
;DOTEST.DO
:<Command line: $0 $1 $2
>
Assuming that the user had input "SiLly" in response to the prompt in test.cmd, the output of the DOTEST command would be:
Command line: SiLly silly SILLY
Note that these two functions , LCS($KBDn) and UCS($KBDn), are the only ones supported on the DO command line.
