;WILDEX - wildcard expansion module
; S. Kluger  04/15/84
;
; Modified 8/23/91 by Howard Goldstein to correct usage instructions
; and shorten code.
;
; This module, for use with SYSLIB, can be used
; to expand a wildcard filename into a table of
; file names as found in current DU:
;
; ENTRY:
; HL = .buffer
; DE = .afn fcb
;
; EXIT:
; HL = number of files
; ACC= zero flag set if error, clear if ok
; the buffer contains (HL) file names of 16 char each
; Char 0 contains the user number!
