 Yes I see, I would have never known about the effect of the flag field and would have plowed ahead and broken down the default message with strtok to get what I wanted. This is far more efficient. It will certainly work for all the RMS return codes so that's mainly what I need.

Note that all this is to get the name as a string at runtime
to get the name at development time one can just do:
$ libr/text/extr=rmsdef/out=rmsdef.h sys$library:sys$starlet_c
$ sear rmsdef.h 98962
#define RMS$_FNF 98962
