## FAPPEND Append component to file

The FAPPEND function appends a new component to the file, returning the component number used. The syntax is:

          R  DATA FAPPEND TIENO {PASS}

DATA is any APL array or an overlay created using OV. 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.

The explicit result is the component number to which the data was written (i.e. the highest existing component number plus 1).

The effect of FAPPEND is similar to FWRITE with a component number of 0 (or omitted).
