The information in this document applies to:
WordPerfect® 5.1 for DOS

Problem

Symptoms: Releases of WordPerfect prior to 12/31/90 did not prevent users from naming a file with a DOS reserved filename (e.g., CON, LPT1, COM1, etc.) Sometimes a customer experienced data loss when he tried to use one of these names. Now that the 12/31/90 release corrects this problem, why is it considered an enhancement rather than a fix? Solutions: Earlier release of WordPerfect assumed that the customer was familiar enough with DOS to know that these filenames were reserved for special purposes or functions of DOS. WordPerfect code didn't check for these reserved filenames and prevent their use, therefore, the code was working as designed. To implement this name checking function, new code was needed in the program. This code was an addition to, not a correction to the already existing code. This is why the change is considered an enhancement rather than a fix.
