No, ASMPUT is essentially dead. The (non-IBM) Windows tools that had been used to create ASMPUT ceased being supported and then ceased being licensable, so it could no longer be supported, which was announced in APAR PI81310. We did try to port it to a different set of tools but soon found it taking a disproportionate amount of effort so that was cancelled. https://www.ibm.com/support/pages/apar/PI81310
It still works to a very limited extent on Windows. To install it you must rename the downloaded install file type to .ZIP before attempting to install. Some function is lost when running in Windows compatibility mode. The ADATA files it expects need to be generated in HLASM 1.4 format, which requires the use of a special ADATA exit.

The Program Understanding Tool (ASMPUT) from the HLASM Toolkit seems to be targeted to platforms no longer supported. Is there an update that runs on Linux or W11? Cross-posted -- Shmuel (Seymour J.)
