Using the command line

You can specify all the input ILIB needs on the command line. The syntax of the command line is:

ilib [options] [libraries] [@responsefile] [objects]

Options
Options that affect the behavior of ILIB
Libraries
The input library to be created or modified
Response file
The name of a text file containing ILIB options
Objects
Commands used to add, delete, replace, copy, and move object modules within the library

The ILIB command line is a free format command line; that is, the input arguments can be specified any number of times, in any order. The only exception is the /FREEFORMAT option, which does have a position restriction. See /FREEFORMAT for more information.

Note:
For compatibility with the OS/2 release of ILIB, a fixed format command line is also supported. To use the fixed format command line, the /NOFREEFORMAT option must be specified immediately following ilib on the command line, or as the first parameter in the ILIB environment variable. The default command line format is free format.

For the purposes of this document, only the free format command line will be described in detail.
