bad substitution Error while renaming Extension
Hi All,

We are in the process of Migrating from AIX 4 to Solaris 10 and getting a Few Errors.

I have been programming in shell but could never establish muself as an expert, hence please need you help.

I am Getting Bad Substitution error in my script, I have isolated the issue and its illustrated as below

Code:
$ FILENAME=TEST_FILE.txt
$ echo $FILENAME
TEST_FILE.txt
$ echo ${FILENAME%.txt}
bad substitution
$

But the above Works absolutely fine in my AIX environment (below)
Code:
$ FILENAME=TEST_FILE.txt
$ echo $FILENAME
TEST_FILE.txt
$ echo ${FILENAME%.txt}
TEST_FILE
$

How can i get this working in Solaris, One thing i noticed is that the Default Shell in My AIX is Korn and in Solaris is Bourn
I tried setting the SHELL variable to Korn in my Solaris machine by setting SHELL=/usr/bin/ksh
but still the same result.

P.s. the above is just an Example, the Shell script uses the ${..........} for much advanced conversions:

Please Help.

info

INFO(1) 							   User Commands							   INFO(1)

NAME

       info - read Info documents

SYNOPSIS

       info [OPTION]... [MENU-ITEM...]

DESCRIPTION

       Read documentation in Info format.

OPTIONS

       -k, --apropos=STRING
	      look up STRING in all indices of all manuals.

       -d, --directory=DIR
	      add DIR to INFOPATH.

       --dribble=FILENAME
	      remember user keystrokes in FILENAME.

       -f, --file=FILENAME
	      specify Info file to visit.

       -h, --help
	      display this help and exit.

       --index-search=STRING
	      go to node pointed by index entry STRING.

       -n, --node=NODENAME
	      specify nodes in first visited Info file.

       -o, --output=FILENAME
	      output selected nodes to FILENAME.

       -R, --raw-escapes
	      output "raw" ANSI escapes (default).

       --no-raw-escapes
	      output escapes as literal text.

       --restore=FILENAME
	      read initial keystrokes from FILENAME.

       -O, --show-options, --usage
	      go to command-line options node.

       --subnodes
	      recursively output menu items.

       --vi-keys
	      use vi-like and less-like key bindings.

       --version
	      display version information and exit.

       -w, --where, --location
	      print physical location of Info file.

       The first non-option argument, if present, is the menu entry to start from; it is searched for in all `dir' files along INFOPATH.  If it is
       not present, info merges all `dir' files and shows the result.  Any remaining arguments are treated as the names of menu items relative	to
       the initial node visited.

       For a summary of key bindings, type h within Info.

EXAMPLES

       info   show top-level dir menu

       info info
	      show the general manual for Info readers

       info info-stnd
	      show the manual specific to this Info program

       info emacs
	      start at emacs node from top-level dir

       info emacs buffers
	      start at buffers node within emacs manual

       info --show-options emacs
	      start at node with emacs' command line options

       info --subnodes -o out.txt emacs
	      dump entire manual to out.txt

       info -f ./foo.info
	      show file ./foo.info, not searching dir
