-
BLOCK
-
specifies that terminal I/O is blocking.
-
NOBLOCK
-
specifies that terminal I/O is non-blocking.
TERMIO controls whether terminal I/O in
line mode SAS is blocking or non-blocking. NOBLOCK, the default, allows other
processes, such as ODS, to execute while the line mode process waits for terminal
input. While NOBLOCK is set, command line recall is limited to one previous
command. Specify TERMIO=BLOCK to enable full command line recall functionality.
