## FRDAC Read component-file access matrix

The FRDAC function returns the access matrix for a file. The syntax is:

          R  FRDAC TIENO {PASS}

TIENO is the tie number you used to tie or create the file (or the tie number returned by APLX if you tied or created it using 0 instead of your own tie number). If you tied the file using a pass number, you must provide the same pass number, as the PASS parameter.

The explicit result is the file's current N by 3 access matrix (which may be empty). See the description of FSTAC for details.
