| 14 | C Abstract |
|---|
| 15 | C XGETUA may be called to determine the unit number or numbers |
|---|
| 16 | C to which error messages are being sent. |
|---|
| 17 | C These unit numbers may have been set by a call to XSETUN, |
|---|
| 18 | C or a call to XSETUA, or may be a default value. |

| 20 | C Description of Parameters |
|---|
| 21 | C --Output-- |
|---|
| 22 | C IUNIT - an array of one to five unit numbers, depending |
|---|
| 23 | C on the value of N. A value of zero refers to the |
|---|
| 24 | C default unit, as defined by the I1MACH machine |
|---|
| 25 | C constant routine. Only IUNIT(1),...,IUNIT(N) are |
|---|
| 26 | C defined by XGETUA. The values of IUNIT(N+1),..., |
|---|
| 27 | C IUNIT(5) are not defined (for N .LT. 5) or altered |
|---|
| 28 | C in any way by XGETUA. |
|---|
| 29 | C N - the number of units to which copies of the |
|---|
| 30 | C error messages are being sent. N will be in the |
|---|
| 31 | C range from 1 to 5. |
