^FUNCPTR

Assign a routine to a delegate

NSupported in Synergy .NET

^FUNCPTR(routine)

Arguments

routine

A subroutine, function, or method path that you want a delegate to call. (a)

Discussion

The ^FUNCPTR data reference operation enables you to assign a subroutine, function, or method to a delegate so you can then call that routine from the delegate.

If routine is not a subroutine, function, or method path, the compiler will report a NOTALLOWED error (“Non-routine path not allowed in ^funcptr”). When trying to match a subroutine, function, or method with parameters to a delegate, make sure the parameter passing convention also matches; otherwise, you'll get a TYPMISMCH error.
