SAR$–Symbolic Access Routines<br />

FIP$HSEC<br />

The highest mass storage sector address assigned to the SDF file used for input or<br />

output. This is a 24-bit field contained in bits 12 to 35 of the word (bit 0 is the<br />

leftmost bit of the word). This field is not currently used.<br />

FIP$NRSEC<br />

The mass storage sector address of the input file to begin reading at. This field is a<br />

full word; however, S1 contains the word offset (FIP$NRWO), which is not part of<br />

the sector address. This field is not used for symbiont files.<br />

FIP$NRWO<br />

The word offset into the mass storage sector address of the SDF input file to begin<br />

reading at. This field is equated to S1 of FIP$NRSEC, and must be set after<br />

FIP$NRSEC is set. Otherwise it will be overwritten. This field is not used for<br />

symbiont files.<br />

FIP$NWSEC<br />

The mass storage sector address of the SDF output file to begin writing at. This<br />

field is a full word; however, S1 contains the word offset (FIP$NWWO) which is not<br />

part of the sector address. This field is not used for symbiont files.<br />

FIP$NWWO<br />

The word offset into the mass storage sector address of the SDF output file to begin<br />

writing at. This field is equated to S1 of FIP$NWSEC, and must be set after<br />

FIP$NWSEC is set. Otherwise it will be overwritten. This field is not used for<br />

symbiont files.<br />
