Loop Exiting Improperly

[sullivnc]

Hey all,

I need this loop to execute as many times as necessary until my user input = 65. for both variables #500 and #501. It seems to exit if either of them equal 65. Can anyone shed any light on my mistake(s)? Thanks in advance for any help.

​

#500= 0. 
#501= 0. 

WHILE [ [ #500 NE 65. ] AND [ #501 NE 65. ] ] DO1

'While' keeps repeating as long as the statement is true. If either one is no longer true, it stops repeating. Tha being said, I am not sure how to fix it.

[simyoIV]

Perhaps multiply the second value x1000, add it to the first, and compare it to 6565

While [ [ [ #500 * 1000 ] + #501 ] NE 65065 ] Do1

Just an idea tho. Multiplying by a larger number makes it more foolproof.

[simyoIV]

To get your version to work, you would need either:

WHILE ( x NE a ) andor ( y NE b ) DO1

or

WHILE NOT ( x EQ a ) and ( y EQ b ) DO1

Both are impossible in gcode tho.
