$Fsterr

The $Fsterr function returns a string containing the prefix and text of the first counting error message or request cancellation message received by the user.

Syntax

This function takes no arguments.

Usage notes

• A null value is returned if no counting error or request cancellation message has been received since:
  • The beginning of the user's Model 204 session
  • The last call to the $ErrClr function
  • Processing a SOUL Open statement
• The maximum length of the returned string is determined by the setting of the ERRMSGL parameter. That parameter defaults to 80 which means a maximum of 79 characters are returned, but ERRMSGL can be set as high as 256 which means up to 255 characters would be returned.
• $Fsterr is not available for Host Language Interface applications.
• The $Fsterr function requires an additional 88 bytes in the fixed portion of the server.

Example

A sample $Fsterr function with an On Error unit follows. To learn about On Error units, see ON units.

begin fsterr.proc: on error print 'The request is ending' print 'The first error message was:' print $fstErr end on get.recs: find all records for which agent = blake end find for each record in get.recs . . end for end
