Parentheses ( )
When you specify this option, the WRITEREAD operation is not retried by the
SeeView program if an error occurs, and the file-system error is returned in the
specified error variable.
If you do not specify error-var, the operation is under the control of standard
SeeView I/O recovery.
Considerations
This command is for advanced scripting purposes.
Example
This example shows the WRITEREAD statement.
Parentheses ( )
The left and right parentheses specify operator precedence and also delimit
designational integer assignment expressions.
Considerations
A designational expression permits integer variable assignment within an expression.
Designational expressions are allowed anywhere expressions are permitted.

,#GetRevision := #esc & "_"
{ PCT read full revision level}
