Re: How are CPU Speed and Overall CPW Related?

Hi Buck,
 
Good suggestion as far as coding technique.  But I just wanted to compare
CPU time.  Foxpro and Delphi don't have a VARYING string type.  They were
required to scan all 50 bytes in the string in order to Trim it.  The
VARYING type with INZ('TEST STRING') allows the RPG %TRIM() BIF to process
only the first 13 bytes (2 which contain the length, and 11 which contain
the text), and bypass scanning the remaining 39 bytes.  I wanted each
program to be as nearly identical as possible, in order to focus on CPU
performance.

Thanks,
 
 Nathan.
