PRB: Unknown Function psrch with Brief Emulation in PWB

MS-DOS    | OS/2

The information in this article applies to:

• Microsoft Programmer's Workbench for MS-DOS, versions 1.0 and 1.1
• Microsoft Programmer's Workbench for OS/2, versions 1.0 and 1.1

SYMPTOMS

When using the Brief emulation feature of the Programmer's WorkBench (PWB) versions 1.0 and 1.1, reinitialization of the TOOLS.INI file will cause a number of unknown functions to appear when you try to use them. In short, most of the unknown functions that may be reported are related to search features such as the psearch switch. The error message associated with this search feature is commonly "Unknown function psrch."

CAUSE

This error occurs only after you use the Initialize function.

The Initialize function discards current macro definitions and rereads the appropriate section of TOOLS.INI. This is not exactly the same as restarting PWB; the Autostart macro is not executed after Initialize. The BRIEF emulation depends on the Autostart macro to define the search functions.

RESOLUTION

To recover the definition of the missing macros, execute the toggle_re BRIEF emulation macro (CTRL+F6). To avoid having to remember to execute this macro, you can add this to the main section of TOOLS.INI:

   reinit:=Initialize Autostart
   reinit:Shift+F8

   psrch:=arg arg "String to Search for" prompt ->can
                                           psearch => :>can cancel
   msrch:=arg arg "String to Search for" prompt ->can
                                           msearch => :>can cancel
   qrepl:=arg arg qreplace
   srchname:="REoff"
