Someone who has been on this list worked for an IVP that published STC's written in COBOL.

Meanwhile, I've known people use even COBOL to write/maintain system code. As for me, I wrote all system code in assembler - bar adhoc stuff, as in to be executed once only (e.g. to convert CICS DFHCSD [?] RDO-defined LU2 connections and sessions to their equivalent assembler DFHTCT entries and macros,) which I then wrote in PL/I to save time. Not sure about PL/I being considered "too slow": it *could* be compiled with the 'optimize' [or similar] option, in the 1980's.
