PRB: Trace Window Appears During Program Execution

• Microsoft FoxPro for Windows, versions 2.5, 2.5a, 2.5b, and 2.6

SYMPTOMS

The Trace window appears during program execution even though no SET STEP ON or SET ECHO ON command was issued.

CAUSE

A SET VIEW TO <viewfile> command was issued, and ECHO was ON when the View file was created.

RESOLUTION

Make sure that ECHO is OFF when you create View files.

MORE INFORMATION

Steps to Reproduce Behavior

1. In the Command window, issue the following commands:

         USE customer
         SET ECHO ON
         CREATE VIEW myview
   

2. Create a program with the following commands:

         WAIT WINDOW "hello"
         SET VIEW TO myview
         WAIT WINDOW "good-bye"
   

3. Run the program above. Note that the Trace window appears with the last line of the program highlighted.

However, the View file also saves other settings (including the current status of SET ECHO), which are then restored with when the SET VIEW TO command is issued. These settings can be viewed through the On/Off, Files, and Miscellaneous panels of the View window.

Other settings saved with the View file are SET PROCEDURE and SET FIELDS.
