This should be really easy, but I can't find an example in the help that
shows what I'm trying to do. I'm mapping an external command to a function
key, but I can't figure out how to include a variable in the command.
Specifically, I want to specify the %programfiles% directory. So far I've
tried:
1) map <F2> :silent ! start "" "$PROGRAMFILES\Inno Setup\ISetup.hlp"
2) map <F2> :silent ! start "" "%PROGRAMFILES%\Inno Setup\ISetup.hlp"
3) let isshelp = $PROGRAMFILES."\\Inno Setup\\ISetup.hlp"
map <F2> :silent ! start "" isshelp
However, they all fail:
1) ":echo $PROGRAMFILES" displays the correct page, but the above command
simply tries to run $PROGRAMFILES as a literal string
2) Each % expands to the source filename rather than being recognized as an
environmental variable
3) isshelp contains the correct string, but it's output literally rather
than treated as a variable
Like I said, I know this is a pitiful problem, but I'm running out of ideas.
What am I doing wrong?
