Used to generate preplanned keyboard input provided that:
1: the CON driver is the input device and
2: a compatible version of ANSI.SYS is the CON driver.
PUSHxx skips the first character (usually a space) following the
command. The remainder of the command line is placed in a stack in
the CON driver. When input is requested from the CON driver, the
contents of a non-empty stack are sent before any actual key input.
The characters of the input line pushed are sent in the order entered
in the line. After multiple pushes, the CON driver sends the
characters of the last push first. If the push would produce a stack
overflow, PUSHxx outputs an error message and does not execute the
push. See ANSI.DOC for information on stack size.
PUSH pushes the remainder of the command line excluding the
PUSHLN pushes the remainder of the command line including the
PUSHM & PUSHMLN work like PUSH & PUSHLN except that bit 7 of each
character is zeroed before the push. The characters '|', '<' & '>';
and control characters, including
the corresponding character from the extended set in the command line.
Characters from the extended set must be pushed with PUSH or PUSHLN.
PUSHxx with no input line (including no space or other character
following the command) will purge the stack.
