The ŒFRDFI function returns information about the creation and last update of a file. The syntax is:
R „ ŒFRDFI 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 a 4 by 2 array of information about
the file. The first column represents
user numbers, and the second timestamps, expressed as seconds since the
start of the millennium (00:00:00, 1 Jan 2000). The rows are:
1. User who created file, Timestamp file was created
2. Reserved (returns ¯1 ¯1)
3. Reserved (returns ¯1 ¯1)
4. User who last updated file, Timestamp file was last updated.
