C Pickups must always be read in an EXCLUSIVE fashion |
| 175 |
IF (pickup_read_mnc) pickup_read_mdsio = .FALSE. |
| 176 |
|
| 177 |
C IO handling is done in one of two senses: |
| 178 |
C (1) outputTypesInclusive=.TRUE. is an "inclusive-or" meaning that |
| 179 |
C one or more write methods can occur simultaneously and |
| 180 |
C (2) outputTypesInclusive=.FALSE. is an "exclusive-or" meaning that |
| 181 |
C only one write method can occur in a given run |
| 182 |
C |
| 183 |
C Since all the *_mdsio flags default to .TRUE. and |
| 184 |
C outputTypesInclusive defaults to .FALSE., the logic here is |
| 185 |
C simple: |
| 186 |
IF ( (.NOT. outputTypesInclusive) |
| 187 |
& .AND. pickup_write_mnc ) pickup_write_mdsio = .FALSE. |
| 188 |
IF ( (.NOT. outputTypesInclusive) |

IF ( (.NOT. outputTypesInclusive) |

& .AND. monitor_mnc ) monitor_stdio = .FALSE. |
| 194 |
|
| 195 |
