DRL KIN (octal 4) - keyboard input last line.

Usage:

drl   kin
zero  data,count
zero  status

Where:

data: is the address of an input buffer. The buffer should be big enough to hold the input line returned (at most 64 words).
count: is the address of the word in which the character count is to be stored. A zero count is returned if there is nothing in the buffer.
status: is a pointer to a one word status return area. Although this is not used by TSS, it must be supplied.

Description:

DRL KIN retrieves the last line of input from the user's UST buffer. Normally this derail would follow immediately the DRL KOUTN sequence, but this is not always necessary. KIN may be repeated to retrieve the same line of input as often as desired; the last line in the buffer will remain there until some additional input or output destroys it. The status parameter is provided for future use.
