What are the naming rules for Proc FCMP functions?

[kwyland1]

Others have posted here about why certain function names don't work.  It is suggested you can't use a reserved name.

The solution to one problem was posted as 'Well I don't know why' - just use a different function name.

I get that.  Like the sample below, 'convert' does not work but _convert would. 

But I would like some reference to know what the naming rules are.  I've searched for days - any help appreciated.

Example:

%let outlib = work;

* Example 2: Return a Character Value;

proc fcmp outlib=&outlib..functions.conversions;

*function lb2kgC(lb) $;   *--this works;

function convert(lb) $;  *-- this does NOT work;

length kg $10;

kg = catt(put((lb/2.2),6.2),'Kg');

return (kg);

endsub;

run;

• Don't use the name of a procedure.
• Don't use the name of a statement (PROC EXPAND has a CONVERT statement).
• Don't use this list of reserved words (it's for the macro facility, but I would say it's just safe to avoid these reserved words everywhere).

• Don't start function name with a number
• No special characters and no spaces

I think I will shoot my code to TS.  The reserved words list for Macros doesn't have the one I tried which is convert.  Also tried conv_.  Bellies up.  If I get a response from TS that anyone could benefit from, I'll post it here.  Thanks.

FYI - if you have a paid SAS license this seems like a good question to ask tech support.

I do - was just trying out communities first
