Introduced in v6.0, Preemptive: yes

Parameter	Type	In/Out	Description
Context	Longint	→	Execution context
Stack_id	Longint	→	stack id or 0
Typelocalglobal	Longint	→	1=local 2=global 3=inter process variable
Index	Longint	→	Index (from 1 to n)
Varname	Text	←	Name of the variable (point to)
TypeLocGlobRes	Longint	←	1=Point to local variable
2=Point	To	←	variable
3=Point	To	←	process variable
PointToStack	Longint	←	Point to stack id (if local variable)
Table	Longint	←	Point to table
Field	Longint	←	Point to field

Description

The command hmX_GET POINTER BY INDEX returns information about pointer variables of a context. The access of the variable stack goes over an index, which is returned by the command hmX_Count Variables. Then you can loop through all variables. The function returns valules only, if it is a pointer variable.

If stack_id equals 0, you will get the local variables-stack from the last executed method. Otherwise, pass the stack_id to read the local variables from the stack.
