Walter Pachl

Walter was for 25 years with the IBM Laboratory Vienna where he worked on several software products such as DITTO, SDF, and a PL/I subset compiler for DPPX. The highlight of his career were the test activities for the REXX Compiler. A fully automated test environment allowed for continuous regression testing and ensured a high quality product.

After he left IBM, Walter worked at an Austrian bank where he started to convert many of the (VM/CMS) REXX tools that we developed and enjoyed in the Lab to TSO/ISPF. Real work was, however, based on PL/I and DB2.
