hmX_Count Variables (Context ; stack_id ; typelocalglobal) → Count

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
Count	Longint	←	Number of variables

Description

The command hmX_Count Variables returns the number of variables in the context. The scope of the variable stack is defined by typelocalglobal. 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.

With the command hmX_GET VARIABLE BY INDEX you will get each variable and it’s content.

Example

The following example returns the number of local variables:

var $vl_count : Integer

$vl_count:=hmX_Count Variables($context; 0; 1)

The following example returns the number of process variables:

var $vl_count : Integer

$vl_count:=hmX_Count Variables($context; 0; 2)
