• Not Able to Display the Variable Contents 
To display the local variable contents, user variables are needed. 
For example, to view the contents of local variable LP000, save it
temporarily as user variable P001. Then execute the instruction
SET P001 LP000, and view the POSITION VARIABLE window for
P001.
• Enabled Only During the Execution of the Defined Job 
The contents of the local variables are enabled only during the
execution of the defined job. 
The local variable field is assured when the defined job is called
(when the job is executed by a CALL or JUMP instruction, or the job
is selected by the menu). Once the job is completed by the
execution of a RET, END, or JUMP instruction, the local variable
data that was set is disabled. However, if a job which uses local
variables itself calls a separate job, then is returned by use of a RET
instruction, the data that was present prior to the CALL instruction
remains in effect and can be used.
Precautions for Variables and Units
As was the case with user variables, note that, depending
on the value of the unit being used, the value of the variable
NOTE
and the value of the actual speed or time an occasion might
not match. Refer to section 3.9.4 "User Variables" on page
3-77.
