first the code

code:

---

$a = "test"
$string = "this is a string with ~$$a~ in it"

; this is just filler to get to the function....
;
if instr($string,"~") <> 0
	? FillVariable($string)
else
	? $String
endif
exit
; This is a function that will look for $variables inside a 
; string, and fill them with their values, for the moment, I 
; am just trying to fill the variable.
Function FillVariable($string)
	DIM $string, $element	;<---this line is playing a major part in the weirdness!
	$string = split($string,"~")
	for each $element in $string
		if substr($element,1,1) = "$"
			$nul = execute('$$trap = $element ? "in execute $$$$trap = $$trap"')
			? "Outside of execute $$trap = " + $trap
		endif
	next
endfunction

---

Everything is working fine with the above code... but since i want to my variables used inside a function, to stay inside the function. I do a DIM of all of the variables that the function uses.

But if i change this line

code:

---

	DIM $string, $element   ;<---this line is playing a major part in the weirdness!

---

to this

code:

---

	DIM $string, $element, $trap	;<---this line is playing a major part in the weirdness!

---

the variable $trap never makes it out of the EXECUTE() command.

[edit]

It appears that any variable defined in an execute() command is defined as a global variable. Shouldn't variables restricted to a subroutine with a DIM command stay with in that subroutine? This is why when i DIM $trap inside the function, and then i do an EXECUTE() with $trap, $trap new value is set at the GLOBAL level, not at the calling DIMed level (does that make any sense?)
