Invalid procedure name

There are restrictions in procedure-naming beyond the rules for naming identifiers. This error has the following cause and solution:

• You attempted to define a procedure, but the name used for the procedure is invalid because the host already uses that identifier for another purpose. For example, if the host application is Microsoft Excel, you can't define a procedure with the name R1C1 because that identifier is already used by Microsoft Excel.

  Choose another name for the procedure.

• Your procedure name is that of a restricted keyword, exceeds 255 characters, or doesnÆt begin with a letter.

  Choose a different name for the procedure.
