- Have you ever written a BASIC program error trapping routine and then
- sat there putting in stuff like IF ERR = 61 THEN PRINT "DISK FULL",
- etc.? It can go on and on... I spent a little time and created a
- random access file which contains all of the error messages from my
- DOS manual. Each record number is the number of the error. Now I tell
- the error trapping routine to open the error file and print the
- message found in record # err.
-
- In this archive you will find the data file (ERROR.DAT), a BASIC
- source file showing an example of how to access the data (EXAMPLE.BAS)
- and a program which will display the messages if you want to see them
- (DEMO.EXE). Everything was done for Microsoft's QuickBASIC, however,
- add line numbers and it will work with interpreted BASIC.
