Defining a User Variable/Constant
A variable or constant is a memory location allocated to store a number.
GML Commander allows you to use user variables and constants in your
program. You can set or modify these values during run-time or test and/
or set variables in your program. You can test variables for a variety of
conditions, for example, greater than (>), less than (<), or equal (=)
conditions.
You must define user variables or constants before they appear as
selections in the Tag Explorer. You define them for you application as you
need them.
Creating, Editing, and Deleting a User Variable or Constant
With the following example, we will show you how to create a user
variable, edit or delete the value, and add it to the General Watch Window.
You can use the same methods for a user constant.
Note: You can define user variables to appear in the tag window even if
the diagram has not been downloaded.
