IBM Alternate Library for REXX on zSeries Version 1.4.0 for use with z/VM



This package enables users to install the Alternate Library in a fast and easy way. Vendors who distribute REXX compiled code may want to add this package to their installation.

Download Description

The Alternate Library is shipped together with the fee-based program product 5695-014 for z/VM. It is designed for REXX developers who want to distribute REXX compiled products. IBM grants you the right to package the Alternate Library with your REXX compiled products. The Alternate Library allows customers who do not own the Library for REXX on zSeries (5695-014) to run REXX compiled code.

Note, however, that the "real" REXX Runtime Library offers many benefits compared to the REXX Alternate Library.
