ID 20868

Invalid symbol after EXIST.

Description

An invalid character is programmed after the EXIST command.

The cause can be the absence of the opening parenthesis immediately after the command, or an invalid character after this square parenthesis. Permissible signs direct after the opening square bracket are 'P' for parameter and 'V' for variable.

A further possible cause of the error is the absence of the closing square bracket if a variable or parameter is unknown.
