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 :(
You can simulate this in FPC as well as TP by using a local typed constant. e.g.
function GetValue: integer;
const value: integer = 0;
begin
Inc(value);
Result:= value;
end;
Successive calls to GetValue() will return 1, 2, 3 etc.
yes, that is exactly what i was thinking of... i just could not find any sample
code in my library... as noted, i have used it and it sounds similar to what the
OP is looking to do... one thing i used to use it for was counting the number of
time that a routine was called during the course of execution... other times i
used it were in relation to recursion IIRC...
NOTE: i've never done this with strings but i would guess it would work, too...
