Ascertaining Keyword Parameters [message #30209]

Hello,

Is there any way to ask an IDL function or procedure what keyword
parameters it accepts? I'd like a function that takes the string name
of an IDL procedure and returns a string array containing the names of
all accepted keyword parameters--something like the "KEYWORDS_ACCEPTED"
function below.

IDL> plotKeywords = KEYWORDS_ACCEPTED('PLOT')
IDL> PRINT, plotKeywords
BACKGROUND CHARSIZE CHARTHICK CLIP COLOR FONT LINESTYLE MULTI NOCLIP
NOERASE NSUM POSITION....

Maybe someone with experience writing IDL system routines knows how to
do this?

Thanks.
