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 an interactive pair. 1 Files specified by infilenum and listfilenum form an 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. |
