⎕FRDCI Read component information

The ⎕FRDCI function returns information about a component. The syntax is:

      R ← ⎕FRDCI TIENO COMPONENT {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 parameter COMPONENT is the component number. This must be an integer in the range Lowest existing component number to Highest existing component number.

The explicit result is a three-element integer vector:

1. The free workspace required to read the component

2. The account number (1↑⎕AI) of the user who last wrote the component.

3. The time at which the component was last written, expressed in seconds since the start of the millennium (00:00:00, 1 Jan 2000).
