What happens if substitution increases the length of that longest record? Is this documented? I believe I once caused an error by lengthening a record by substitution, even though the increased length was still less than the value of the DD LRECL option. Reported to SR; Got WAD.

Re: Variable length records for SYSIN data sets
How the internal reader handles instream data sets is documented here: https://www.ibm.com/docs/en/zos/2.4.0?topic=reader-record-length-sysin-data-sets https://www.ibm.com/docs/en/zos/2.4.0?topic=reader-sysin-record-formats Also note that JES2 and JES3 work differently. But bottom line, for JES2, everything is based on the actual length of each record written. This gets a little tricky with TSO SUBMIT (or ISPF SUBMIT) commands. SUBMIT always writes records with a record length of 80. So all instream data sets are RECFM F and LRECL 80 when SUBMIT is involved. For other uses of the internal reader, as already stated, the RECFM is F if all records are the same length (including if there are 0 or 1 records). If the lengths of the record vary, the RECFM is V. CC is supported if the JCL (records) are written with CC (eg using IEBGENER from a RECFM VBM data set) and the RECFM is adjusted accordingly (fun rules for if there are both ASA and machine CC). Instream data set LRECL for RECFM F data sets is the length of the records. If there are 0 records (null data set), it is the length of the DD * or DD DATA card (very old rule). For RECFM V data sets, the LRECL is set to the length of the longest record in the instream data. Note for all of this, each instream data set is processed separately. So each data set can have a different LRECL/RECFM. As for LRECL on the DD * or DD DATA card, JES2 ignored this until APAR OA60172. Starting with that APAR, if an instream data set is RECFM F and LRECL is specified, JES2 will pad records for the data set up to the LRECL specified. This helps when using instream data concatenated to other RECFM F data sets. This is not to say that LRECL was totally ignored on a DD * or DD DATA card. When the DCB access method is used to read an instream data set (vs ACB/RPLs), the size of the buffer the access method passes to JES is determined by the LRECL specified on the DD. Also note that in a concatenation, the RECFM is determined by the first DD in the concatenation. A customer trying to concatenate a RECFM V data set to a RECFM F instream data set with LRECL specified led to APAR OA62088. You see the fix for APAR OA60172 added too much padding to an instream data set. Basically, LRECL on the instream DD statement in that case included the 4 byte RDW prefix but the ACB/RPL interface passes the actual length so padding to LRECL made the record 4 bytes too long. Hopefully this enlightens a bit on how all this works.

Re: Variable length records for SYSIN data sets
My very first computer program was about 30 feet of paper tape for the IBM 610 at Notre Dame in Sep 1959 when I was a Sophomore in EE. It calculated the value of a 4x4 determinant. The first output on the Selectric was four characters WOW! I sat in the computer room when not in class for three days until the only other user came in, and he helped me to understand the difference between program and data, and showed me that the first character on my paper tape told the reader to look for a control character, and in the fifth from end character it found a control character that told the reader to print out the tape characters as instructions, and thereby printed the last four instructions in my program: Carriage Return, Line Feed, Carriage Return, Print Accumulator, WOW! (The second CR was to get the Selectric all the way back to the left before it printed the result.)

Re: Variable length records for SYSIN data sets
Looks like it's utilizing only those DCB parameters that are support for SYSIN datasets, and RECFM is not one of them.

Variable length records for SYSIN data sets
I have a goal to concatenate a data set of variable length records (RECFM=VB,LRECL=204) with an instream data set of fixed length characters. My though was to add RECFM=V to my instream DD, i.e.: //INFILE DD DISP=SHR,DSN=MY.VB.FILE // DD *,RECFM=V,LRECL=204 The RECFM is rejected as being conflicting with a SYSIN dataset: IEFC009I KEYWORD RECFM IS MUTUALLY EXCLUSIVE WITH KEYWORD SYSIN ON THE DD STATEMENT And yet the following section of the manual, "SYSIN data set" has discussion of SYSIN data sets where "the record format is variable": https://www.ibm.com/docs/en/zos/2.5.0?topic=ssds-sysin-data-set But how do I actually make the SYSIN dataset variable length?
