Was not intentional. Just a thing of habit.

It isn't immediately obvious what isn't working in this example and you don't give us any indication of what you think it is doing wrong.
Yes, I have to be more clear. I got it working though. It was a silly mistake of not watching the correct text that I was replacing; it was actually working all along. Smilie

Note that the <space> after <orth> will be treated as a field separator, not as part of the string to be replaced. Note also that with many of your search patterns (many of which contain <space>s) and replacement patterns (many of which contain <space>s), using code like the above will give you more than 2 fields in the created array unless you use a different array element separator and add an ERE to your split() call specifying the character(s) in your separator as the element separator.
Yes, found this to be the case. And I've decided to keep the code as it was for now-this is a little too deep for me atm and not entirely necessary for the program to work... As for the other code, I've shortened it up abit.

Just a note: I've started to make this program in C++; it seems that it could benefit from the speed and features. Already, the C++ program can open a file and extract, replace, and print a few text combinations; so you may not see me posting for a little bit in the Shell Programming Forum, but I will still be using awk for the many things that it can do!

lksh

LKSH(1) 						    BSD General Commands Manual 						   LKSH(1)

NAME

     lksh -- Legacy Korn shell built on mksh

SYNOPSIS

     lksh [-+abCefhiklmnprUuvXx] [-+o opt] [-c string | -s | file [args ...]]

DESCRIPTION

     lksh is a command interpreter intended exclusively for running legacy shell scripts.  It is built on mksh; refer to its manual page for
     details on the scripting language.  It is recommended to port scripts to mksh instead of relying on legacy or idiotic POSIX-mandated behav-
     iour, since the MirBSD Korn Shell scripting language is much more consistent.

LEGACY MODE

     lksh has the following differences from mksh:

     o	 lksh is not suitable for use as /bin/sh.

     o	 There is no explicit support for interactive use, nor any command line editing or history code.  Hence, lksh is not suitable as a user's
	 login shell, either; use mksh instead.

     o	 The KSH_VERSION string identifies lksh as ``LEGACY KSH'' instead of ``MIRBSD KSH''.

     o	 lksh only offers the traditional ten file descriptors to scripts.

     o	 lksh uses POSIX arithmetics, which has quite a few implications: The data type for arithmetics is the host ISO C long data type.  Signed
	 integer wraparound is Undefined Behaviour.  The sign of the result of a modulo operation with at least one negative operand is unspeci-
	 fied.	Shift operations on negative numbers are unspecified.  Division of the largest negative number by -1 is Undefined Behaviour.  The
	 compiler is permitted to delete all data and crash the system if Undefined Behaviour occurs.

     o	 The rotation arithmetic operators are not available.

     o	 The shift arithmetic operators take all bits of the second operand into account; if they exceed permitted precision, the result is
	 unspecified.

     o	 The GNU bash extension &> to redirect stdout and stderr in one go is not parsed.

     o	 The mksh command line option -T is not available.

     o	 Unless set -o posix is active, lksh always uses traditional mode for constructs like:

	       $ set -- $(getopt ab:c "$@")
	       $ echo $?

	 POSIX mandates this to show 0, but traditional mode passes through the errorlevel from the getopt(1) command.

     o	 lksh, unlike AT&T UNIX ksh, does not keep file descriptors > 2 private.

CAVEATS

     lksh tries to make a cross between a legacy bourne/posix compatibl-ish shell and a legacy pdksh-alike but ``legacy'' is not exactly speci-
     fied.

     The set built-in command does not have all options one would expect from a full-blown mksh or pdksh.

     Talk to the MirOS development team using the mailing list at <miros-mksh@mirbsd.org> or the #!/bin/mksh (or #ksh) IRC channel at
     irc.freenode.net (Port 6697 SSL, 6667 unencrypted) if you need any further quirks or assistance, and consider migrating your legacy scripts
     to work with mksh instead of requiring lksh.
