Summary: Local named parameters not scoping correctly in subroutines
Initial Comment:
The scoping of a named parameter used in a do/while loop behaves differently
when the do/while loop is inside a subroutine or not inside a subroutine. In
the example code below, the do/while loop decrements a local named parameter
used as a counter variable. This loop works when used in the main body of the
gcode but this same code does not work when used inside of a subroutine. When
used inside the subroutine #<i> reverts back to it's previous value after
leaving the o<TestLoop> scope.
SAMPLE GCODE WORKING EXAMPLE
----------------------------
(THIS WORKS, PRINTS 5 4 3 2 1 0 CORRECTLY )
#<i>=5
o<MainLoop> do
#<i> = [ #<i> - 1 ]
(PRINT, i = #<i>)
o<MainLoop> while [ #<i> GT 0 ]
M02
SAMPLE GCODE DOES NOT WORK EXAMPLE
----------------------------------
( THIS DOES NOT WORK, GOES INTO INFINITE LOOP )
o<TestSub> call
M02
o<TestSub> sub
#<i>=5
o<TestLoop> do
#<i> = [ #<i> - 1 ]
(PRINT, i = #<i>)
o<TestLoop> while [ #<i> GT 0 ]
o<TestSub> endsub
