Overview The OS/VS2 MVS38J file sorting function is provided by the IBM S360 SORT/MERGE product included in the public domain version of the MVS38J Operating System. The sort/merge product provides exit processing that facilitates calling external user programs at various points within the sort/merge phases such as SORT INPUT PHASE (e.g. add/change/delete input records) or MERGE OUTPUT PHASE (e.g. add/change/delete…

Sorting in MVS38J
Overview The OS/VS2 MVS38J file sorting function is provided by the IBM S360 SORT/MERGE product included in the public domain version of the MVS38J Operating System. Most sorting requirements are satisfied by executing a SORT/MERGE utility job step in a batch environment to order a set of data before applying a processing or reporting activity. Also, the IBM S360 SORT/Merge…
ISPF Option 6 in MVS38J
Overview Using ISPF 2.x (Wally Mclaughlin’s ISPF-like product), Option 6 is a common panel utilized to execute TSO commands under ISPF on your Hercules/MVS 3.8J system. Simply, type the command plus any parameters (if any), and press ENTER. While developing CLISTs , especially one with two or three parameters where one parameter is a dataset name, retyping that command for…
FTP in MVS38J
Fellow MVS38J enthusiasts! Before getting too involved in this post, MVS38J TK4- systems already have FTP enhanced support enabled by Jürgen Winkelmann. But, if you have a non-TK4- OS version, such as TK3 or TK3 derivative, this post may be of interest… When I first read about MVS38J FTP capabilities in the different online forums, the FTP facility from Jason…
GETMSG in MVS38J
GETMSG – Get ISPF Message for MVS38J /ISPF / Hercules(current version 0.9.00 2019-09-11) Overview GETMSG is a simple ISPF utility for use under ISPF 2.x (ISPF-like product from Wally Mclaughlin). Specifically, this utility will fetch an ISPF message from MLIB and return each message component (e.g. short and long message content) in ISPF Shared variables for CLISTs access. This utility…
ISRZ00 in MVS38J
ISRZ00 – ISPF Generic Messages for MVS38J / Hercules(current version 1.2.00 2022-07-09) When developing application dialogues under ISPF 2.0 (Wally Mclaughlin’s ISPF-like product) on a Hercules/MVS38J system, some form of error processing and messaging is most likely an application requirement. Even when quickly developing a productivity tool! ISPF 2.0 (referred to ISPF in this post) message facility displays a short…
DYNBLOAD in MVS38J
Overview For those MVS 3.8J enthusiasts using the supplied MVT COBOL (referred to as COBOL) compiler, you probably discovered that called programs must be statically linked and resolved before executing the problem (calling) program. This results in a composite load module that includes the COBOL problem program itself, COBOL ILB* subroutines and other subroutines called by the COBOL problem program.…
LISTDSJ for MVS 3.8J
Overview LISTDSJ – Dataset Information for MVS3.8J / Hercules(current version: 2.0.01 2024-04-15) Inspired by LISTDS and other similar TSO CPs that display dataset attribute information and, in particular, the absence of a LISTDSI-type TSO CP in MVS 3.8J, I started to focus on creating one to fill this void! Some weeks later, I finalized my functional and design thoughts to…
CALNDRs in MVS38J
Overview In late 2018, in the interest of interfacing with Wally’s Mclaughlin’s newly ISPF-like product, I wrote a simple application using different solution sets for educational and learning purposes to demonstrate the versatility of using diffent programming languages. CALNDRs (Calendars) in MVS38J is a post that discusses that application using the compilers offered and supplied with MVS 3.8J in conjunction…
PARMs in MVS38J
Overview Passing parameters to a program is a common practice when using and/or developing subroutines. The parameter communications protocol (API) can take different forms depending on established APIs or newly defined APIs. This post will focus on two types of parameter layouts encountered in a TSO / ISPF environment when invoking a program or command: Parameter layout used by TSO…
