ProcedureBlock
Usage
The class definition specifies whether methods in the class are procedure blocks by default. To override that default, and specify that a given method is a procedure block, use the following syntax:
Method name(formal_spec) As returnclass [ ProcedureBlock ]
{
//implementation
}
Or (equivalently):
Method name(formal_spec) As returnclass [ ProcedureBlock=1 ]
{
//implementation
}
Otherwise, to specify that a given method is not a procedure block, use the following syntax:
Method name(formal_spec) As returnclass [ ProcedureBlock=0 ]
{
//implementation
}
Details
This keyword specifies that an ObjectScript method is a procedure block.
Within ObjectScript, methods can be implemented as procedure blocks or not. Procedure blocks enforce variable scoping: methods cannot see variables defined by their caller. New applications use procedure blocks; non-procedure blocks exist for backwards compatibility.
Default
If you omit this keyword, the value of the class-level ProcedureBlock keyword is used.
