So then I can't use ROUTINE_INFO on it?

IDL> info = ROUTINE_INFO('median',/FUNCTIONS,/PARAMETERS)
% Attempt to call undefined procedure/function: 'MEDIAN'.
% Execution halted at: $MAIN$

I'm writing a procedure that you pass a function name to as a string
parameter, and then that function is used later on in the procedure. I'm
trying to include a check for cases where the caller includes keywords
but the function does not accept keywords, most likely a user written
function. The most obvious way seems to be ROUTINE_INFO, i.e.

takeskeywords =
((ROUTINE_INFO(functname,/FUNCTIONS,/PARAMETERS)).NUM_KW_ARG S GT 0)

but it seems as if that does not work for system routines. Any other
suggestions?

Thanks,

John
