DOCUMENT:Q94837 12-JUN-2001 [utilities] TITLE :PWB Extension Converts Selected Text to Uppercase Letters PRODUCT :Microsoft Programming Utilities PROD/VER:MS-DOS:1.0,1.1,2.0; OS/2:1.0,1.1 OPER/SYS: KEYWORDS:kb16bitonly ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Programmer's Workbench for MS-DOS, versions 1.0, 1.1, 2.0 - Microsoft Programmer's Workbench for OS/2, versions 1.0, 1.1 ------------------------------------------------------------------------------- SUMMARY ======= The text below demonstrates the process to create a Programmer's WorkBench (PWB) extension to convert one selected line of text to uppercase. Note that nothing appears to happen if the cursor is on a different line than the selected line. MORE INFORMATION ================ To load and use the extension, perform the following five steps: 1. Copy REVERSE.MXT into the same directory as PWB. By default on an MS-DOS system, this is the BIN subdirectory. By default on an OS/2 system, this is the BINP subdirectory. 2. Modify the TOOLS.INI file to place a load command in the [PWB] section. For example, [pwb] load:[path\]reverse 3. Start the PWB editor. 4. Select the text to convert to uppercase letters. The selection must be on one line. 5. From the Case menu, select Lower to Upper. The source code for this PWB extension is as follows.
