ERROR_LINE

 Returns the line number for the latest error encountered by VAXTPU.  The
 value returned by ERROR_LINE is only meaningful inside an error handler.
 The value outside of an error handler is indeterminate.

 If a procedure was compiled as part of the compilation of a buffer or
 range, ERROR_LINE determines the line number by counting from the
 beginning of the buffer or range.  Therefore, the line number may not be
 the same as the line number counting from the beginning of the procedure.
 If a procedure was returns the value 1.

 Syntax

    integer := ERROR_LINE

 Parameters

    none

 Example

 The following code fragment is an error handler that uses ERROR_LINE to
 report where the error occurred:

    ON_ERROR
      MESSAGE (ERROR_TEXT);
      MESSAGE ("Error on line " + STR (ERROR_LINE);
      RETURN;
    ENDON_ERROR;
