What does this error message mean? I mean, other than 'An invalid index key length has been specified. The length of a key for an .IDX index must be between 1 and 100 characters. The length of a key for a .CDX index must be between 1 and 254 characters.' VFP 3.0b help file.

I got this message when I tried to add an index to a table in a dbc. The index I tried to add was named 'JobName', the type was 'Regular' and the expression was 'JobName(cJob_Id)' where JobName is a procedure defined in the dbc's Stored Procedures. It returns the character name field from the Job table for the record id passed to it.

This table also has 8 other indexes. Six of those indexes are on secondary key fields that are 6 characters in length. One index is DELETED() and the last index contains a procedure similar to the index that I'm trying to define.

Am I placing too much of a burden on the .CDX file of this table?
