PRB: Cannot Release Procedure's FXP if Class Definition in PRG (192960)

SYMPTOMS

In a program file, when using the SET PROCEDURE TO command to call a procedure file that has a Class Definition in it, issuing a RELEASE PROCEDURE command in the program file will not release the procedure's FXP file even after the program has been run. If the procedure file does not have any Class Definition in it, RELEASE PROCEDURE will work as expected.

RESOLUTION

Use the CLEAR ALL command to release the procedure's FXP file.

STATUS

This behavior is by design.

Steps to Reproduce Behavior

  1. Create a program file named mytest containing following code: 
          FUNCTION TestFunction

      o=CREATEOBJECT("cTemp")
      o.SomeMethod()

      RETURN

      DEFINE CLASS cTemp AS Custom

         FUNCTION SomeMethod(lcText)
            lcText=IIF(type("lcText")="C",lcText,"HelloWorld")
            WAIT WINDOW lcText
         RETURN

      ENDDEFINE
  2. In the Command window, run the following commands: 
          CLEAR ALL
      CLOSE ALL
      CLEAR PROG

      SET PROCEDURE TO mytest
      ?SET("PROCEDURE")     && The name of the procedure file returned
      DO TestFunction

      RELEASE PROCEDURE mytest
      ?SET("PROCEDURE")     && Nothing returned
  3. Go to Explorer and find mytest.fxp and try to delete the file. Note that the FXP file cannot be deleted, yet you cannot access either the function in the PRG or the class.
