So, I know that the first question is likely to be 'why on Earth would you want to do this?!', but I will ask anyway.
Is there anyway to force an increase to the number of vertices that are accepted by USERSYM from 49? A symbol I made (Galaxy) had 51 vertices, and I was most irked when I discovered that the maximum number was 49.
Normally I am not bothered with such things, and ignore them, but I can only guess that this is an archaic function that hasn't been touched in years.
Regards
David

The USERSYM function was already there in IDL V2.0 (maybe before!). At this time every memory byte saving was important.
Please do not be archaic ! You may use IDL Object graphics (e.g. IDLgrSYMBOL), introduced in IDL V5 or 6, or even IDL Graphics function (e.g. SYMBOL keyword) introduced in IDL V8.0.
