Steps to Reproduce Behavior

Run the following code from a program (.prg) file:
Local lni
For lni = 1 to 10
	local array laTest[1]
	=alines(laTest, '')
	_Calcmem = lni  && store counter to survive clear all
	Clear all
 	?SYS(1011), int(_calcmem)
	Local lni
	lni = _calcmem
Endfor
RETURN
				
After the code runs, two numbers appear. The first column indicates the memory handles as reported by SYS(1011). The second number indicates the iteration of the loop. Note that Visual FoxPro adds one handle per iteration.
