Another way to do this is to XEQ a separate command file from your initial
command file with input redirection.  Your second command file would have
the while loop with an input statement to set a variable to the line.  If
you insist on a single self contained command file you can create the
"called" command file before executing it with echo statements and output
redirection.

XEQ INPROC.COMMAND.SYS < INFILE

                   Steve,

                using the input against an ascii file can be done, but for
that you need
                to copy the original file contents into a message file. The
message file
                uses destructive reads (each record is deleted after a read
command).


                Good luck,
