I remember that in the late 80s there was a syntax checker available for PL/I also. It ran with the ISPF editor and marked at least typing errors (prior to the times of syntax highlighting). I believe, all people wanting a IDE for the mainframe are waiting for a version of WDz fulfilling their needs.
