Pragma {flag} for Initialization, Monitoring, Creation of symbols
{flag [] [off|on]}
can be a combination of the following flags:
noinit: The variable will not be initialized.
nowatch: The variable can not be monitored
noread: The variable is exported to the symbol file without read permission
nowrite: The variable is exported to the symbol file without write permission
noread, nowrite: The variable will not get exported to the symbol file
With the „on" modifier, the pragma operates on all subsequent variable declarations
until it is ended by the pragma {flag off}, or until overwritten by another {flag
on} pragma.
Without the „on" or „off" modifier, the pragma operates only on the current variable
declaration (that is the declaration that is closed by the next semicolon).
Examples for use of pragma {flag}:
Initialization and monitoring of variables:
The variable a will not be initialized and will not be monitored. The variable b will not
be initialized:
VAR
a : INT {flag noinit, nowatch};
b : INT {flag noinit };
END_VAR
VAR
{flag noinit, nowatch on}
a : INT;
{flag noinit on}
b : INT;
{flag off}
END_VAR
