[sqr-users] RE: let vs move discussion part deux

["White, Denise" <DEWhite@vicr.com>]

I was taught what Don said - that 'move' is more efficient than 'let'.  To be 
more specific, I was taught that 'move' is three times faster than 'let'.  I 
wasn't told anything about numeric vs. character values.  This is interesting - 
I am always interested in programming as efficiently as possible (even though 
some people think I'm weird because computer processors are so fast that the 
differences are minuscule).  I routinely use 'move' wherever possible (unless I 
have a group of statements together, have to use 'let' in some of them, and 
want them to line up and look pretty!).

Don,

I cordially disagree.  Unless brio has changed anything lately, numeric 
assignments are faster with move but character assignments are faster with 
let because there is more overhead associated with the move command.  Maybe 
someone from brio/sqribe in Ohio can give the definitive answer on this.

As for searching the sqrug database, there isn't really that much and 
everything I see in the database is 4 years old.

in this message http://www.sqrug.org/sqr-users/sqrusers_97/msg00690.html the 
values are all numeric.
ditto http://www.sqrug.org/sqr-users/sqrusers_97/msg00696.html

Actually, just to be nit-picky, "move" is more efficient than "let" for
all simple assignments.  Just like "add" is more efficient than let,
"subtract" is more ...etc.

For complex assignments that would take multiple "single-purpose"
commands, then "let" is more efficient.

See archives for many discussions thereof.
