Passing answers to external program from KSH

I have asked this before but I haven't had any luck so far getting this to work. I use RCS(revision control system). When it runs if I pass the value 'unlock' to $3 its reassigned to $unlock. When I run the command (rcs -u'version number' 'filename') ti will ask me 1-(Do you want to break the lock y/n?) then 2-(The reason for breaking the lock) 3-(Enter a '.' period on a blank line when done) All I want to pass to the program is (y,production install,'.') When I run rcs manually and I simply hit enter on the line asking if I want to unlock the file, it will terminates and says the file is still locked which is what is occurring. It will not pass the answers I have put into the script. It seems to act like I simply hitting the enter key. Does anyone have any ideas?

Code:

if [[ $unlock = "unlock" ]]; then
print $PS1 "rcs -u${Reqvers} $Reqfile"
rcs -u${Reqvers} $Reqfile<<PAUL
y
PROD install of $acr
PAUL
 fi

rcsdiff

RCSDIFF(1)						      General Commands Manual							RCSDIFF(1)

NAME

       rcsdiff - compare RCS revisions

SYNOPSIS

       rcsdiff [ -biwt ] [ -cefhn ] [ -rrev1 ] [ -rrev2 ] file ...

DESCRIPTION

       Rcsdiff runs diff (1) to compare two revisions of each RCS file given.  A file name ending in ',v' is an RCS file name, otherwise a working
       file name. Rcsdiff derives the working file name from the RCS file name and vice versa, as explained in co (1). Pairs consisting of both an
       RCS and a working file name may also be specified.

       All options except -r have the same effect as described in diff(1).

       If  both  rev1 and rev2 are omitted, rcsdiff compares the latest revision on the trunk with the contents of the corresponding working file.
       This is useful for determining what you changed since the last checkin.

       If rev1 is given, but rev2 is omitted, rcsdiff compares revision rev1 of the RCS file with the contents of the corresponding working file.

       If both rev1 and rev2 are given, rcsdiff compares revisions rev1 and rev2 of the RCS file.

       Both rev1 and rev2 may be given numerically or symbolically.

EXAMPLES

       The command

	       rcsdiff	f.c

       runs diff on the latest trunk revision of RCS file f.c,v and the contents of working file f.c.
