There should be a file in libc source called ctype.c. It has the definition of the table. The standard place on SVR2 is /usr/src/lib/libc/port/gen/ctype.c. Hope it helps.

ixdigit() is supposed to return true iff its argument is 0..9 a..f A..F.

I presumed (and my manual agreed), that it returns true for Hex digits, i.e. 0-9, a-f & A-F, and false for any othe argument. It IS documented in our IS/3 manual, and in the PC/IX manual as well.
