variable question
Message #1 Posted by Vincze on 23 Aug 2007, 8:48 a.m.

In recent Datafile, Joe Horn state that program run quicker on 35s if you store the number in a variable that if you just have it in the program. Anyone understand why? I would think it would be the other way around as you do not need to recall something.

There is overhead associated with keystroke programming each digit is handled and processed into a storage register to come up with the final number. Recalling a number can be less overhead (may be equivalent if the # of digits input is low but is not for larger number of digits.
