Syntax
WE
Parameters
None.
Description
This command terminates a WHILE loop initiated by any of the WG, WH,
WL or WY commands.
Up to 100 While loops can be nested, but they must follow the general rule
of multiple loops: last one opened is the first one closed.
NOTE
To be accepted, WE must be placed on a different line than WG, WH, WL
or WY. To improve program clarity, it is recommended to place the WE
on a separate line.
NOTE
All While loop commands (WG, WH, WL and WY) must be terminated
with a WE command.
Returns
None.
