Syntax
IND(channelno{,ERR=lineref}{,END=lineref})
Description
The IND() function returns the pointer of the current record on channelno. For TCP/IP or UDP socket
connections, it returns the socket number.
If the file pointer is at the end of the file, an !ERROR=2 is generated.
Some file types do not return anything as the index.
Example
4910 LET A=IND(CHANNEL,END=9000)
