You need some familiarity with both languages in order to do a conversion.\u003cbr\u003eThis 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.\u003cbr\u003eTSO-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.\u003cbr\u003eCLIST 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.\u003cbr\u003eThe 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.\u003cbr\u003eI'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.\u003c\/p\u003e","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Paperback","offer_id":45511332200599,"sku":"9781508668497","price":2218.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781508668497.webp?v=1767171693","url":"https:\/\/atlanticbooks.com\/products\/tso-clist-to-tso-rexx-conversion-handbook-9781508668497","provider":"Atlantic Books","version":"1.0","type":"link"}
