A procedure constant that is initialized with no procedure value.
0
Procedure Public Const
Use this constant to test if a procedure variable is set. By default, all procedure variables are initialized to the NoProcedure variable.
The following example demonstrates how to change an error handling procedure:
Procedure SetErrorHandling(proc): void public
proc : Val Procedure
{
if proc=NoProcedure
m_procError=DefaultErrorHandling;
else
m_procError=proc;
endif
}
