Refering to compound variables with a variable name

Hello,

Here is my problem using KSH
I have a set of compound variables, let say cmp_var1 cmp_var2
The names of these variables are stored in an indexed array.
How can I access the subfields of these compound variables ?
I tried:
Code:
set -A cmp_varnames=(cmp_var1 cmp_var2)
for cmp in ${cmp_varnames[*]}
do
eval ${${cmp}.field}
done

That does not work, I tried a few other things, no luck.
Thanks for helping

XmStringByteCompare(library call)										 XmStringByteCompare(library call)

NAME
XmStringByteCompare -- A compound string function that indicates the results of a byte-by-byte comparison SYNOPSIS
#include <Xm/Xm.h> Boolean XmStringByteCompare( XmString s1, XmString s2); DESCRIPTION
This function is obsolete and exists for compatibility with previous releases. XmStringByteCompare returns a Boolean indicating the results of a byte-by-byte comparison of two compound strings. In general, if two compound strings are created with the same (char *) string using XmStringCreateLocalized in the same language environ- ment, the compound strings compare as equal. If two compound strings are created with the same (char *) string and the same font list ele- ment tag set other than XmFONTLIST_DEFAULT_TAG using XmStringCreate, the strings compare as equal. In some cases, once a compound string is put into a widget, that string is converted into an internal form to allow faster processing. Part of the conversion process strips out unnecessary or redundant information. If an application then does an XtGetValues to retrieve a com- pound string from a widget (specifically, Label and all of its subclasses), it is not guaranteed that the compound string returned is byte- for-byte the same as the string given to the widget originally. s1 Specifies a compound string to be compared with s2 s2 Specifies a compound string to be compared with s1 RETURN
Returns True if two compound strings are identical byte-by-byte. RELATED
