i'm trying to understand what you mean by

i've done something that i think is what you speak of but it was in Borland's 
Turbo Pascal... at least TP6... i don't remember how we did it though and can't 
find any sample code in my library :(

what happened is that the value did not get cleared between invocations of the 
routine and subsequent executions could use the value already stored... this 
breaks, of course, if the memory area for the routine is cleared first...
