loop.
[Example 1] DWEQ 1 0 Repeat the commands up to an EDDO command while
variable 1 contains “0.”
:
600 ITER
:
Forcibly switch the control to an EDDO command and
perform end judgment, if flag 600 is ON.

(Output, flag)
Optional Optional SLCT Prohibited Prohibited CP
[Function] Branch to the step next to any WH

or WS

command that exists before an EDSL
command and whose condition is satisfied, or to the step next to an OTHE command if
none of the conditions are satisfied.
A SLCT command must be followed by a WH

, WS

or EDSL command.
A maximum of 15 nests are supported.
(Note) Using a GOTO command to branch out of or into a SLCT-EDSL syntax is prohibited.
[Example 1] SCPY 1 ‘Right’ Assign ‘right’ to columns 1 and 2.
:
600 SLCT Jump to a W

whose condition is satisfied.
WSEQ 1 ‘Right’
:
If ‘right’ is stored in columns 1 and 2, this command
will be executed.
WSEQ 1 ‘Left’
:
If ‘left’ is stored, this command will be executed.
OTHE
:
If the content of columns 1 and 2 is neither of the
above, this command will be executed.
EDSL If flag 600 is OFF, the processing will move here upon
execution of any of the conditions.
