Re: Clear entire field vs substring

Instead of "field = *blancs;" use "clear field;" It should be faster for varying, because instead of filling the field with spaces it will just set the leght to zero. A very important difference if you want to concatenate some data to the field.
And, the intention of "clear" seems pretty clear, without any aditional explanation :-)

Forgetting the details, is it better to clear an entire field or to
clear a subscripted portion of the field. Which incurs more overhead?

If clearing the whole field satisfies your functional requirements,
just clear it. This would be my recommendation even if the
performance was twice as slow. Worry first about readability and
maintainability. Unless you are already writing the simplest-LOOKING
code, and you are ACTUALLY EXPERIENCING performance that is too slow,
don't resort to complicated-looking code.
