Fortran Output Conversion Error (OUTCONERR)?

» close window

The Question is:

Using Compaq Fortran V7.5-2630-48C8L in writing to an internal character string
 I got this error:
%FOR-E-OUTCONERR, output conversion error unit -5  file Internal Formatted
 Writede  user PC 000
%TRACE-E-TRACEBACK, symbolic stack dump follows

Question: What is Fortran lun -5 ?
(and where is it documented ?)
Thank you for your help in acquiring this information.

The Answer is :

  Please contact the customer support center for assistance, as
  details of the Fortran code involved and the apparent attempted
  (and failing) conversion will be required.
  Without a source code reproducer, the OpenVMS Wizard must point
  to the following documentation:
    "During a formatted output operation, the value of a particular
    number could not be output in the specified field length without
    loss of significant digits. If /CHECK=NOOUTPUT_CONVERSION is in
    effect (see Section 2.3.11), the severity is I (program continues).
    When /CHECK=NOOUTPUT_CONVERSION is in effect or if no ERR address
    is defined for the I/O statement encountering this error, the
    program continues and the entire overflowed field is filled with
    asterisks to indicate the error in the output record."
  The OpenVMS Wizard has seen reports of this OUTCONERR output
  conversion error resulting from one of problems with carriage
  control in an output record.  If there is no carriage control,
  please open the file with CARRIAGECONTROL='LIST'.  Alternatively,
  please verify the placement of the appropriate Fortran carriage
  control in the record.
  Please also review the capabilities of the debugger, as this
  tool can help you localize the error and (in cases such as
  this one) review the arguments.
