Synopsis
The optimal reference for companies moving to multiple operating systems that need to learn new command languages, and for firms using a single operating system that need to choose the best command language for a particular operation. It compares and contrasts the five major command languages used today - DOS/OS/2 Batch Language, CLIST, DCL, PERL and REXX - and offers practical guidance on choosing the best command language for developing a specific application. The book also offers detailed treatment on portability between different command languages, and shares step-by-step methods for converting programs to different command languages. This book should be of interest to systems managers.
