JG,
I use the lines below to do keyword checking and it works great. I recommend
Ronn Kling's book, it will get you up to speed quickly.

typedef struct {
IDL_KW_RESULT_FIRST_FIELD;
int degree;
} KW_RESULT;
static IDL_KW_PAR kw_pars[] = { IDL_KW_FAST_SCAN,
{"DEGREE",IDL_TYP_LONG,1,IDL_KW_ZERO,0,IDL_KW_OFFSETOF(degree)},
{NULL}
};
KW_RESULT kw;
IDL_KWProcessByOffset(argc,argv,argk,kw_pars,0,1,&kw);
