Re: DS subfield not honoring watch

[Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx>]

Even with a fresh start, it happened again.  I checked the field just 
before the MOVEL and it was blank, I added a breakpoint a couple of 
lines later, and I hit F12.  It hit the breakpoint and not the 
watchpoint, and but the value was changed  to '1'.

Even stranger, I move the field to a screen field, display it with 
EXFMT, and then move it back.  Even if I don't change the field on the 
screen, I still trigger the watchpoint.  So it's as if the debugger is 
holding a cached value of CSSHAL and the MOVE into the data structure 
field is not updating that cached value.

It's really quite odd.  If I get time I'll trim it down to the bare 
essentials and see if it continues.
