Dynamically Loadable Modules, ISSET(), LOCAL, LPARAMETERS, PARAMETERS, PRIVATE, PUBLIC, SET STRICT, TYPE()

Description

With SET LOCAL ON, any variables being created dynamically (SET STRICT must be OFF) are created as LOCAL variables rather than PRIVATE variables. This protects you from variable scoping issues. When LOCAL is ON the PARAMETERS statement is also treated as a LPARAMETERS statement. By default, SET LOCAL is ON.

Introduced in Lianja v4.1.

Example

function calledfunc
	if isset(cVar1)  // returns .F.

	if isset(cVar2)  // returns .T.
		? cVar2
	endif
endfunc
 
set local on  // default
cVar1 = "I'm local"
private cVar2
cVar2 = "I'm private"
