This kind of problem must have come up in this group before, but here it
is anyways.
If I call the IDL systime function with the utc keyword:
print, systime(/utc)
on IDL versions older than 5.4 I get the expected 'keyword not
supported' error message, since, well, it's not supported, right? The
error message pops up when the function containing the systime call is
compiled, so testing e.g. !version.release before executing the systime
call doesn't work.
The only solution I have come up with so far is to put the systime call
inside a call_function call:
print, call_function( 'systime', /utc)
This will compile (I will still need to test for !version.release before
actually executing the statement of course).
This to me looks like a somewhat illegitimate use of call_function. Not
that I mind bending the rules a bit, but are there any other (better)
techniques of dealing with keywords that don't work in all IDL versions.
