Contributor: SWAG SUPPORT TEAM SECTION 4 - Vintage Pascal This document contains information that is most often provided to users of this section. There is a listing of common Technical Information Documents that can be downloaded from the libraries, and a listing of the five most frequently asked questions and their answers. TI407 Using the serial port in a Pascal application TI152 Interupt handler for 3.X and lower TI226 Async routines for versions 3.X and lower TI232 Absolute disk read for version 3.x and lower Q. "Are any of the ToolBox programs that shipped with versions 3.0 and 4.0 still available. For instance, can I get an upgraded copy of the Database ToolBox or the Editor ToolBox." A. No. These programs are no longer in any form from any company. If you want to get a copy of them, you would need to purchase them from a current owner. Q. "Can the ToolBox programs be used from version 7.0?" A. It depends. As a rule, the answer is yes, all you need to do is recompile and they will run fine. This is totally fortuitous, however, and Borland has, and will, do nothing to update these programs. See TI1728 for help upgrading the Editor ToolBox. Q. "How can I convert my Turbo Pascal 3.0 program to version 7?" A. There is a file called up UPGRADE.ZIP which is available on the forums. This can help in the process of upgrading the files. Most of the code from version 3.0 will run fine under 7.0, but not all of it. Q. "When I use the Turbo Vision editors unit from Version 6.0 I never see the numbers 3, 4, 6 and 7 when I try to type them in." A. This was a bug in the first version of TP6.0. The fix is available in EDITOR.PAT, found in LIB1. Q. "What ever happened to FreeMem and FreePtr?" A. These Turbo Pascal 5.x identifiers are no longer used by the heap manager. Simply delete references to FreeMin from your code. If you're using routines that use FreePtr to compress the heap or perform other implementation-dependent operations on the heap, you'll need to update these routines. (If you just need to lower the top of memory in order to do an Exec, you can call the SetMemTop procedure from the Turbo Vision Memory unit.) See the Programmer's Guide for more information about how the heap manager works.
