Hi Emmanuel,
Agree and not only that: 0.00835 actually becomes an
intelligible:parm.VAL/DESC

No one suggested this but ... you can also put your constant as input!
0.00835 then becomes D, etc...  with just that change you saved 12 chars!

Hey everyone,
I need to evaluate a somewhat complicated conditional statement in a calc record. Presently I need to evaluate:
 field(CALC, "(235>B&& 5>D&& 5>E) ? (B*0.00835 - 0.7> A + (C-B)*0.25 ? B*0.00835 - 0.7: A + (C-B)*0.25): 0")
where the letters are input variables. When I load the record I get the error
Can't set "VOLT:PID.CALC" to "(235>B&&  5>D&&  5>E) ? (B*0.00835 - 0.7>  A + (C-B)*0.25 ? B*0.00835 - 0.7: A + (C-B)*0.25): 0"
Error at or before ")" in file "MagnetCtrlApp/Db/MagnetCtrl.db" line 113
Does CALC not support nested evaluations? Perhaps I need a subroutine record? Any advice would be greatly appreciated.
Cheers,
Andrew
