Best known initially for its mainframe applications, REXX is today included with OS/2 and is quickly gaining prominence as a powerful and flexible language. Devoted solely to the OS/2 version of REXX, this volume aims to give readers - even those who are new to REXX - the tools to construct programs of varying levels of sophistication. The book also covers debugging and associated programs such as REXXTRY, PMREXX and the REXXUtil Dynamic Link Library.
