SETSYSTEMVAL acting strange - VMS

Another answer;

I added a couple of lines, to define the global symbol "manually", not
relying on QUICK at all (although the book says SETSYSTEMVAL is global)
as suggested;

    LET T-CMD = "DELETE/SYMBOL/LOCAL MDS$MILL_NO"
    RUN COMMAND T-CMD REFRESH SCREEN
    IF NOT SETSYSTEMVAL("MDS$MILL_NO",T-MILL,SYMBOL)
      THEN ERROR "*E* Could not set Mill number. Please contact IS."

         LET T-CMD = "MDS$MILL_NO :== " + T-MILL   ;NEW
         RUN COMMAND T-CMD REFRESH SCREEN          ;NEW

    LET T-HOLD-MILL = GETSYSTEMVAL("MDS$MILL_NO",SYMBOL)
    IF T-HOLD-MILL <> T-MILL
      THEN ERROR "*E* Could not set Mill number. Please contact IS."

Got the same results with QDESIGN - it's not just setting the symbol as
"local", it's actually storing & resetting
it on exit. However, compiled and doing a "RUN COMMAND", it works fine.

Thanks!
