Input Functions 13-35
The output argument is the status of the CALL. It has the following values:
•
0 – Successful
•
1 – Disabled
•
2 – Bad input parameter
•
3 – DF1 not enabled
•
4 – String too small
•
5 – String is not dimensioned
To disable this CALL, a zero must be PUSHed into the first input parameter. All
other parameters are ignored but must still be PUSHed.
Whenever an attempt is made to read a remote node, the status of the read is placed
into the input word 1, bits 0-7. The possible status codes are shown in Table 13.12.
The status is valid when the module sets the input file word 0, bit 10.
