Description toggles case sensitivity on the current port, or displays its present condition when used without options.

For a system to run with the ability to be "case sensitive" and "case insensitive" among different users, the entire operating system must be structured so that the data base remains independent of case. All lookups for commands, item types, codes, etc. are "case insensitive" by default. This basically means that all dictionary lookups will be case insensitive.

Two macro versions of this verb, "case-on" and "case-off", are provided to direct comparisons within data files to be case sensitive or case insensitive.

The type of comparisons performed on data within attributes using Access will be determined by the status of the case bit.

The default is case insensitive.

To remain case sensitive, add the "case-on" verb to the user logon macro.
