| 18 | ! Description of Parameters |
|---|
| 19 | ! --Input-- |
|---|
| 20 | ! IWHICH - Index of item desired. |
|---|
| 21 | ! = 1 Refers to current error number. |
|---|
| 22 | ! = 2 Refers to current error control flag. |
|---|
| 23 | ! = 3 Refers to current unit number to which error |
|---|
| 24 | ! messages are to be sent. (0 means use standard.) |
|---|
| 25 | ! = 4 Refers to the maximum number of times any |
|---|
| 26 | ! message is to be printed (as set by XERMAX). |
|---|
| 27 | ! = 5 Refers to the total number of units to which |
|---|
| 28 | ! each error message is to be written. |
|---|
| 29 | ! = 6 Refers to the 2nd unit for error messages |
|---|
| 30 | ! = 7 Refers to the 3rd unit for error messages |
|---|
| 31 | ! = 8 Refers to the 4th unit for error messages |
|---|
| 32 | ! = 9 Refers to the 5th unit for error messages |
|---|
| 33 | ! IVALUE - The value to be set for the IWHICH-th parameter, |
|---|
| 34 | ! if ISET is .TRUE. . |
|---|
| 35 | ! ISET - If ISET=.TRUE., the IWHICH-th parameter will BE |
|---|
| 36 | ! given the value, IVALUE. If ISET=.FALSE., the |
|---|
| 37 | ! IWHICH-th parameter will be unchanged, and IVALUE |
|---|
| 38 | ! is a dummy parameter. |
|---|
| 39 | ! --Output-- |
|---|
| 40 | ! The (old) value of the IWHICH-th parameter will be returned |
|---|
| 41 | ! in the function value, J4SAVE. |
