Good progress Peter. The debugger turning the bit on seems to be... wrong. Interestingly wrong ("oh, we're in the debugger, let's do something different...") :-)
The bit is only ever set (to zero or one, as appropriate) once by LE per "environment that needs to be established" (my wording). If the first program is C/C++, the bit is on, and left on. If it is explicitly turned off, it will stay turned off. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
