Your example, scottn, works fine.
But my real case is a little bit more complicated...here a portion of it:
Code:
for I in UL_LAT UR_LAT LR_LAT LL_LAT UL_LON UR_LON LR_LON LL_LON ; do
            # Convert every value from 71 4 17.92 in 71.071644443
            DEGREES=$( echo ${I} | awk '{ print $1 }' )
            MINUTES=$( echo ${I} | awk '{ print $2 }' )
            SECOND=$(  echo ${I} | awk '{ print $3 }' )
            eval $I=$( echo "scale=9; ${DEGREES}+${MINUTES}/60+${SECOND}/3600" | bc )
        done

Executing that I obtain:
Code:
(standard_in) 1: illegal character: U
(standard_in) 1: illegal character: L
(standard_in) 1: illegal character: _
(standard_in) 1: illegal character: L
(standard_in) 1: illegal character: T

(standard_in) 1: illegal character: L
(standard_in) 1: illegal character: O
(standard_in) 1: illegal character: N
(standard_in) 1: syntax error

Any ideas?

mkmanifest

MKMANIFEST(1)						      General Commands Manual						     MKMANIFEST(1)

NAME

       mkmanifest - create a shell script to restore Unix filenames

SYNOPSIS

       mkmanifest [ files ]

DESCRIPTION

       Mkmanifest creates a shell script that will aid in the restoration of Unix filenames that got clobbered by the MSDOS filename restrictions.
       MSDOS filenames are restricted to 8 character names, 3 character extensions, upper case only, no device names, and no illegal characters.

       The mkmanifest program is compatible with the methods used in pcomm, arc, and mtools to change perfectly good Unix  filenames  to  fit  the
       MSDOS restrictions.

EXAMPLE

       I want to copy the following Unix files to a MSDOS diskette (using the mcopy command).

	    very_long_name
	    2.many.dots
	    illegal:
	    good.c
	    prn.dev
	    Capital

       Mcopy will convert the names to:

	    very_lon
	    2xmany.dot
	    illegalx
	    good.c
	    xprn.dev
	    capital

       The command:

       mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital > manifest

       would produce the following:

	    mv very_lon very_long_name
	    mv 2xmany.dot 2.many.dots
	    mv illegalx illegal:
	    mv xprn.dev prn.dev
	    mv capital Capital

       Notice that "good.c" did not require any conversion, so it did not appear in the output.

       Suppose	I've  copied  these files from the diskette to another Unix system, and I now want the files back to their original names.  If the
       file "manifest" (the output captured above) was sent along with those files, it could be used to convert the filenames.
