C |

C MDSREADFIELD - read model field from direct access global or tiled MDS file |
6 |
C MDSWRITEFIELD - write model field to direct access global or tiled MDS file |
7 |
C MDSFINDUNIT - returns an available (unused) I/O channel |
8 |
C MDSREADVECTOR - read vector from direct access global or tiled MDS file |
9 |
C MDSWRITEVECTOR - write vector to direct access global or tiled MDS file |
10 |
