call tsacc(length, message)
This subroutine enables a TSS program to get the uninterpreted contents of the terminal input buffer. It is of particular use in obtaining the command line used to invoke a program, or when working with a VIP terminal in forms mode.
Previous message residue remains in the input buffer since the buffer is not initialized prior to the transfer of data to the caller.
Input messages are terminated by a carriage return (octal 015).
