A batch file is a text file on a DOS diskette that contains VMF
commands. When you run a batch file, you must leave the diskette
in the drive until all of the commands have completed. You need
an operating system such as AIX or PC DOS to create a batch file.
You can supply the batch file up to 10 variables on the exec
command. The variables are sequentially assigned the symbols
through %9 beginning with the batch file name. For example, if
you enter
exec listit /hdO/usr/bin
on the command line, then symbol %0 is assigned the variable
listit and symbol %1 is assigned the variable /hdO/usr/bin. If the
batch file named listit contains
li %1
then the li command displays the contents of directory /usr/bin on
minidisk hdO.
The following are descriptions of the VMF commands. A
description of each command is available on the system when VMF
is active by entering
