SUMMARY
=======

All methods are read-only at run time. You can, however, have several methods
and decide at run time which method to execute. This article shows you how.

Step-by-Step Example
--------------------

1. Create a new form.

2. Place a command button (Command1) on the form, and add the following code to
  its Click event:

     lcTemp=ThisForm.gcCurrentclk
     &lcTemp

3. Place an Option Group on the form, and add the following code to its Click
  event:

     IF This.Value=1
       ThisForm.gcCurrentclk="ThisForm.Click1"
     ELSE
       ThisForm.gcCurrentclk="ThisForm.Click2"
     ENDIF

4. Create a new form property called gcCurrentclk, and assign ThisForm.Click1 to
  gcCurrentclk.

5. Create a new Form method called Click1, and place the following in the
  Form.Click1 method:

     WAIT WINDOW "Click #1"

6. Create a new method called Click2, and place the following code in the
  Form.Click2 method:

     WAIT WINDOW "Click #2"

7. Run the form.

The option group determines which Click method for the command button will
execute.

NOTE: The Click event for the command button does not have to be a method of the
current form. For example:

  gcCurrentclk="DO myprog.PRG" would execute a program.
  gcCurrentclk="oMyclass.Click1" would execute a method of an external class.
  gcCurrentclk="WAIT WINDOW" would execute a wait window.
