Thanks & thanks :)

It's old parser and I'm afraid there's not much documentation for it. The ones I've used are:
http://hektor.umcs.lublin.pl/~mikosmul/computing/articles/kommander-introduction.html
http://www.kde.me.uk/index.php?page=kommander-tutorial
help:/kommander/
Finally, lots of trial-errors.

IIRC there'no "else" in old parser - just plain if/endif.
There's switch/case/case/.../end structure, but it may need a bit tweaking to work in the example above.
Also presetting certain variables before "if", like below, might work?

set certain globals
reset other globals
@if(@exec(id -u))
 reset certain globals
 set other globals
@endif

>From what I've learned from trial-errors, a crucial point with old parser is that there are two separate logic flows: Logic flow of Kommander, which is controlled by "@" statements and which is in sync with GUI. And logic flow of the shell script spooled to batch, which is comprised of direct shell commands (without @), and which are run literally in spool-to-batch fashion. The logic flow within this batch script is consistent within itself, but it's completely separate and parallel to Kommander logic flow. 

So, to prevent confusion I try follow this rule of thumb:
Within each kommander script either stick to batch-spooled direct shell commands, or stick to "@" prefixed commands, but don't mix the two within the same script.

So, AFAIK the if/endif example above will not work as intended if "set" and "reset" commands are direct shell commands.

Hope it's useful. (And hope it's correct...) :)
