LINE

Process Function

SYNTAX: a = LINE(terminal #)

PURPOSE: To return the status of an input on a STB-26 terminal board.

REMARK S: The terminal # has a one-to-one correspondence with the terminals on the STB-26 terminal board.

This feature eases documentation and troubleshooting. Refer to Card M anual for terminal number

range.

A 1 is returned when a line is logic high, 0 when logic low.

The LINE function is similar to the BIT function in that individual I/O bits or channels can be read.

It differs in that it is used specifically with the STB-26 terminal boards and it executes much faster.
