This section lists error messages that may be displayed when input or internal errors are
encountered. The number to the left of each error message represents an internal error
number that is not displayed. If the error occurs inside a Try...EndTry block, the error
number is stored in system variable errornum. Many of the error messages are self-
explanatory and do not require descriptive information. However, additional information
has been added for some error messages.
