FRELATE
NM and CM callable.
Determines whether a file pair (on any device) is interactive,
duplicative, or both interactive and duplicative.
Syntax

| U16 I16V I16V |
| intordup:=FRELATE(infilenum,listfilenum);|
________________________________________________
Functional Return
intordup 16-bit unsigned integer (assigned functional
return)
Returns values indicating whether the two files
referenced are interactive and/or duplicative:
Bits Value/Meaning
15:1 0 Files specified by infilenum and listfilenum do
not form an interactive pair.
1 Files specified by infilenum and listfilenum form
an interactive pair.
0:1 0 Files specified by infilenum and listfilenum do
not form a duplicative pair.
1 Files specified by infilenum and listfilenum form
a duplicative pair.
Parameters
infilenum 16-bit signed integer by value (required)
Passes the file number of the input file.
listfilenum 16-bit signed integer by value (required)
Passes the file number of the list file.
Operation Notes
A device file is interactive if it requires human intervention for all
input operations; this is necessary to establish the person/machine
dialog required to support a session.
A device file is duplicative if all input operations are echoed to a
corresponding display without intervention by the operating system
software.
The interactive/duplicative attributes of a file pair do not change
between the time the files are opened and closed.
(KSAM) This intrinsic cannot be used for KSAM files. If called for a
file created as a KSAM file, CCL (1) is returned.
Condition Codes
CCE (2) Request granted.
CCG (0) Request denied. Infilenum and/or listfilenum
corresponds to $NULL (a logical file that contains
no data). No data can be read from this file, and
all data written to it is discarded. Interactive
or duplicative functions do not apply.
CCL (1) Request denied. An error occurred.
