C***DESCRIPTION C From the book "Numericl Methods and Software" C by D. Kahaner, C. Moler, S. Nash C Prentice Hall 1988 C Abstract C Allows user control over handling of individual errors. C Just after each message is recorded, but before it is C processed any further (i.e., before it is printed or C a decision to abort is made), a call is made to XERCTL. C If the user has provided his own version of XERCTL, he C can then override the value of KONTROL used in processing C this message by redefining its value. C KONTRL may be set to any value from -2 to 2. C The meanings for KONTRL are the same as in XSETF, except C that the value of KONTRL changes only for this message. C If KONTRL is set to a value outside the range from -2 to 2, C it will be moved back into that range. C C Description of Parameters C C --Input-- C MESSG1 - the first word (only) of the error message. C NMESSG - same as in the call to XERROR or XERRWV. C NERR - same as in the call to XERROR or XERRWV. C LEVEL - same as in the call to XERROR or XERRWV. C KONTRL - the current value of the control flag as set C by a call to XSETF. C C --Output-- C KONTRL - the new value of KONTRL. If KONTRL is not C defined, it will remain at its original value. C This changed value of control affects only C the current occurrence of the current message.

To find out if more than one file is being C used, one must use the XGETUA routine. C C Description of Parameter C --Output-- C IUNIT - the logical unit number of the (first) unit to C which error messages are being sent. C A value of zero means that the default file, as C defined by the I1MACH routine, is being used.

C The following table shows how each message is treated, C depending on the values of KONTRL and LEVEL. (See XERROR C for description of LEVEL.) C C If KONTRL is zero or negative, no information other than the C message itself (including numeric values, if any) will be C printed. If KONTRL is positive, introductory messages, C trace-backs, etc., will be printed in addition to the message.

C***DESCRIPTION C From the book "Numericl Methods and Software" C by D. Kahaner, C. Moler, S. Nash C Prentice Hall 1988 C Abstract C XSETUA may be called to declare a list of up to five C logical units, each of which is to receive a copy of C each error message processed by this package. C The purpose of XSETUA is to allow simultaneous printing C of each error message on, say, a main output file, C an interactive terminal, and other files such as graphics C communication files.
