Read access right
Syntax:
<Result>=GETVARAP(<name>,<access>)
Meaning:
<result>
GETVARAP
<name>
<access>
Example:
Program code
DEF INT result=0
result=GETVARAP("$TC_MAP8","WB")
IF (result < 0) GOTOF error
The value 7 is returned as result. This corresponds to the key switch position 0 (= no access
protection).
Note
GETVARAP can be used, for example, to implement a checking program that checks the
access rights expected by the application.
