These calls are used to position any type of file to a point relative to its current position or to a specific record number. DPOSN is equivalent to the FMGR call POSNT; DXPOS is equivalent to EOPSN.
DPOSN(dcb,err,nur[,rec][,erlc])

nur | |
| record number. A variable containing either the number of |
| records to skip forward (positive value) or backwards (negative |
| value), or the absolute record number to which the file is to be |
| positioned (positive integer only). The rec parameter |
| determines how nur is interpreted. For DXPOS, nur is a |
| doubleword variable with the same meaning. |
rec | |
| is the number of records to skip. If rec is not zero, nur is |
| interpreted as an absolute record number. |
