call_procedure with a dynamically created arguments list? [message #50617]

I have already discussed this with a few of you but wanted to see if
anyone else might know a way of doing the following:

Is it possible to do something like:

foo = "bar"
bla = 'blu"
args=[]
if (N_ELEMENTS(foo) ne 0) then
args=[args, foo]
if (N_ELEMENTS(bla) ne 0) then
args=[args, bla]

CALL_PROCEDURE('some_proc', args)

So, the goal is to build dynamically an arguments list that will be
passed in to CALL_PROCEDURE, CALL_FUNCTION or CALL_METHOD. (I want to
avoid EXECUTE)

thanks,

PS: My goal is to write a transparent wrapper for IDL functions. So, I
would like that when using the wrapper or not, "everything" (including
error message) stays the same.

PS2: David: Yeah, I still havent given up on this. ;-)
