evaluating an expression with mixed data types

[Bern Ertl]

I have to implement the following :

%WorkPeriod = 3000000000&&
LOCAL lTransition AS LONG, sTransitionDate AS STRING, qfBaseDate AS QUAD

...

lTransition = (VAL( sTransitionDate) * %WorkPeriod - qfBaseDate) \ %WorkPeriod

The expression should be evaluated as a QUAD and then assigned to a LONG variable (QUAD upper limit > expression > LONG upper limit will be true before the last division). Is it necessary (or more optimal/efficient) to use CQUD at any point? Like so:

lTransition = (CQUD(VAL( sTransitionDate)) * %WorkPeriod - qfBaseDate) \ %WorkPeriod

[Michael Mattias]

LOCAL tDate AS QUAD
  tDate = VAL(sTransitionDate) 
  lTranstion = (tDate * %workPeriod - qfbasedate) \ %WorkPeriod

Probably what the compiler is doing internally anyway, except I doubt it does VAL as a quad, so there's probably an extra numeric conversion going on in the expression.

So beat the rush and control it yourself this way?
