{ "item_title" : "TSO CLIST to TSO REXX Conversion Handbook", "item_author" : [" Gabriel F. Gargiulo "], "item_description" : "This book is for the programmer who needs to convert a program written in TSO-CLIST to TSO-REXX in the z/OS TSO/ISPF environment. You need some familiarity with both languages in order to do a conversion.This book will show the correspondences, or lack of them, between CLIST language features and REXX language features. CLIST language features are shown on the left-hand page, with the corresponding REXX language feature on the facing, right-hand page.TSO-CLIST dates back to the beginning of TSO in 1971. It truly is a legacy language. IBM continues to support it because so many of its customers have active, functioning CLIST programs in use.CLIST language is found only in one environment, the z/OS TSO/ISPF environment. Experience programming with CLIST is not readily transferable to any other environment. The REXX language is found mostly in the z/OS TSO/ISPF environment, and in QMF, CICS, DOS/VSE, and Netview. Knowing REXX makes you more valuable to your employer.The number of programmers who can understand CLIST language is diminishing. It is a good business decision to convert CLIST programs, where possible, to REXX programs.I'm sure most programmers will remember the nightmare of having to fix a program that is so old that no one left alive knows what the program is expected to do.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/50/866/849/1508668493_b.jpg", "price_data" : { "retail_price" : "24.29", "online_price" : "24.29", "our_price" : "24.29", "club_price" : "24.29", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
