Removing GRAB.COM From Memory |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: Is there a way to remove GRAB.COM from memory? Solutions: Most of us are aware of the fact that, in some situations, once GRAB.COM has been loaded, it cannot be removed. Development states that this is caused by contention over keyboard interrupts. GRAB.COM captures the interrupt when it is installed. When another program is loaded, the interrupt is taken by that new program. When Grab is invoked with the hotkey sequence Alt-Shift-F9, Grab takes back the interrupt and sets a flag. Once that flag has been set, GRAB.COM cannot be removed. If GRAB is not invoked after it is loaded, it does not take back the interrupt and set a flag, so it can be removed. The only way to unload GRAB.COM from memory is to reboot/restart the computer. In some instances, the /R option will work, but it is dependent upon the customer's setup. That is why the /R option is not documented. It isn't guaranteed that Grab will be removed from memory with this option. If the user attempts to remove Grab, but is unable to do so the message "Unable To Remove Screen Capture Utility" will be displayed. One customer who was unable to unload Grab with /R after exiting a program such as WordPerfect or DrawPerfect was able to correct the problem by starting Grab with /C0. The TSR Manager included in Office 3.01 can be used to remove GRAB.COM from memory. Previously, GRAB could only be removed from memory by rebooting. The steps are as follows: 1. Create a batch file with a name such as GRABBER.BAT that contains the following command lines: c:\wp51\grab *c:\wp51\wp.exe 2. Inside Office Shell, set up the menu as follows: Menu Item: WP5.1 with Grab.com Default Directory: C:\WP51 Program Name: TSRM.EXE Startup Options: @Grabber.bat This method will unload GRAB automatically when you exit WP. Note: The batch file must contain the "*" before the WP command line, and the "@" must be included in the Startup Options for this to work properly. Also, the path command must contain the path for the location of the WP.EXE, GRAB.COM, and TSRM.EXE. By using this method, GRAB will be unloaded automatically when you exit WP. |
