2 FUNCTION J4SAVE (IWHICH, IVALUE, ISET)
3 C***BEGIN PROLOGUE J4SAVE
5 C***PURPOSE Save or recall global variables needed by error
7 C***LIBRARY SLATEC (XERROR)
8 C***TYPE INTEGER (J4SAVE-I)
9 C***KEYWORDS ERROR MESSAGES, ERROR NUMBER, RECALL, SAVE, XERROR
10 C***AUTHOR Jones, R. E., (SNLA)
14 C J4SAVE saves and recalls several global variables needed
15 C by the library error handling routines.
17 C Description of Parameters
19 C IWHICH - Index of item desired.
20 C = 1 Refers to current error number.
21 C = 2 Refers to current error control flag.
22 C = 3 Refers to current unit number to which error
23 C messages are to be sent. (0 means use standard.)
24 C = 4 Refers to the maximum number of times any
25 C message is to be printed (as set by XERMAX).
26 C = 5 Refers to the total number of units to which
27 C each error message is to be written.
28 C = 6 Refers to the 2nd unit for error messages
29 C = 7 Refers to the 3rd unit for error messages
30 C = 8 Refers to the 4th unit for error messages
31 C = 9 Refers to the 5th unit for error messages
32 C IVALUE - The value to be set for the IWHICH-th parameter,
34 C ISET - If ISET=.TRUE., the IWHICH-th parameter will BE
35 C given the value, IVALUE. If ISET=.FALSE., the
36 C IWHICH-th parameter will be unchanged, and IVALUE
37 C is a dummy parameter.
39 C The (old) value of the IWHICH-th parameter will be returned
40 C in the function value, J4SAVE.
