BPXWDYN requires several ALLOCs and a CONCAT. Grrr! But the programmer must special-case the single-catenand case. Why can't BPXWDYN (actually, SVC 99, I suppose) recognize that case, do very little, and succeed rather than failing? Only with BPXWDYN can I allocate a mixed concatenation of Classic data sets and UNIX files/directories. COBOL ASSIGN? -- gil
