Common DOS Errors

In my years experience in programming with CA-Clipper, the most common DOS errors encountered are Dos Error 2, 3, 4, 5 and 32. 

However, I have noticed posts on comp.lang.clipper regarding other DOS errors. So here's the full list of DOS errors and my recommended action (if any) to take :

	Error No.	Description	Sugggested Action
	1	Invalid function number
	2	File not found	Make sure that the named file is present in the relevant directory.
	3	Path not found	Check Autoexec.bat to ensure the path is correctly set up.
	4	Too many open files (no handles left)	Increase the FILES statement in Config.sys (or Config.nt - for Windows NT). If you are using Novell Netware, don't forget to have the same FILES HANDLES statement in Shell.cfg or Net.cfg.
	5	Access denied	If you are using 5.3a, click here to read Jo French's comments on the false error message.
