Important Notice
The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
Invalid name (ERR: 81)
■ The rules of naming an ISAM object (such as a table, column,
or index) are different from the rules for naming a Visual
Basic object (such as a variable or procedure). For example,
ISAM names:
• Have no more than 30 characters.
• Use only the characters A-Z, a-z, and 0-9.
• Begin with an alphabetic character.
■ Possible solution:
• Verify that your ISAM object adheres to the ISAM
naming conventions defined above and change the
reference as required.
■ If you need additional help, move the cursor to a keyword
and press F1 to open the Help window.
