c-----------------------------------------------------------------------
7
c subroutines xerrwv, xsetf, and xsetun, as given here, constitute
8
c a simplified version of the slatec error handling package.
9
c written by a. c. hindmarsh at llnl. version of march 30, 1987.
10
c this version is in double precision.
12
c all arguments are input arguments.
14
c msg = the message (hollerith literal or integer array).
15
c nmes = the length of msg (number of characters).
16
c nerr = the error number (not used).
17
c level = the error level..
18
c 0 or 1 means recoverable (control returns to caller).
19
c 2 means fatal (run is aborted--see note below).
20
c ni = number of integers (0, 1, or 2) to be printed with message.
21
c i1,i2 = integers to be printed, depending on ni.
22
c nr = number of reals (0, 1, or 2) to be printed with message.
23
c r1,r2 = reals to be printed, depending on nr.
25
c note.. this routine is machine-dependent and specialized for use
26
c in limited context, in the following ways..
27
c 1. the number of hollerith characters stored per word, denoted
28
c by ncpw below, is a data-loaded constant.
29
c 2. the value of nmes is assumed to be at most 60.
30
c (multi-line messages are generated by repeated calls.)
31
c 3. if level = 2, control passes to the statement stop
32
c to abort the run. this statement may be machine-dependent.
33
c 4. r1 and r2 are assumed to be in double precision and are printed
35
c 5. the common block /eh0001/ below is data-loaded (a machine-
36
c dependent feature) with default values.
37
c this block is needed for proper retention of parameters used by
38
c this routine which the user can reset by calling xsetf or xsetun.
39
c the variables in this block are as follows..
40
c mesflg = print control flag..
41
c 1 means print all messages (the default).
42
c 0 means no printing.
43
c lunit = logical unit number for messages.
44
c the default is 6 (machine-dependent).
45
c-----------------------------------------------------------------------
46
c the following are instructions for installing this routine
47
c in different machine environments.
49
c to change the default output unit, change the data statement
50
c in the block data subprogram below.
52
c for a different number of characters per word, change the
53
c data statement setting ncpw below, and format 10. alternatives for
54
c various computers are shown in comment cards.
56
c for a different run-abort command, change the statement following
57
c statement 100 at the end.
