How to read the 2nd last record of a VSAM file? (The file size is huge and we don't know the key)
HCL,
3218In the house keeping section of an MVS assembly language program, like the one below STM R14,R12,12(R13) BASR R12,R0 USING *,R12,R11 LA R11,2048 LA R11,2048(R11,R12) .... .... 1. What if BASR R12,R0 IS NOT PRECEDE USING *,R12,R11? 2. USING (base address), REGISTER does USING directive says assembler to treat particular Register as a base register with the mentioned base address..in the above case * i.e current location counter..well if that is the case why we need BASR R12,R0 ? 3. What if I write like STM R14,R12,12(R13) BASR R12,R0 LA R11,2048 LA R11,2048(R11,R12) USING *,R12,R11 there is no address resolution being calculated in both LA statements so is it a right way to set Base register?..will there be any issues with Domain regarding R11 and R12?

INCLUDE is used ONLY on MVS/ESA Version 4 or higher systems to name an INCLUDE group. An INCLUDE group is a set of one or more valid JCL statements that are stored together in a JCLLIB data set or a system procedure library, and that are read in and used to replace the INCLUDE statement itself within the job. Any number of INCLUDE statements can be used in a job, but the name field value used on each should be unique within the job. The INCLUDE statements can appear in a job anywhere after the JOB statement, but may not appear between a CNTL and ENDCNTL JCL statement.
Suppose if there are a set of statements and each has a word “value” in it, if I want to display all these statements so that the word “value” is aligned, then how do I code this in rexx?
