The FEXERR function retrieves an Information Builders error message. It is especially useful in a procedure using a command that suppresses the display of output messages.

An error message consists of up to four lines of text. The first line contains the message and the remaining three contain a detailed explanation, if one exists. FEXERR retrieves the first line of the error message.
