Indirect variables in Bash

Hello,
I've spent hours this morning reading various past forum posts and documentation pages but I can't find exactly what I need.

I'm trying to call a variable with a variable in the name without having to make a third variable.

For example:

Code:
path=AB
legAB=50

leg$path

I want to be able to call leg$path variable and get the value "50"


I am aware that if I created another variable I could do this using the ${! } notation:

Code:
var=leg$path
echo ${!var}=50

However, I want to be able to miss out this last step. Is this possible?
Thanks,
Dan

NAME
buildapp - application to create common lisp images SYNOPSIS
buildapp --output OUTPUT-FILE [--flag1 value1 ...] DESCRIPTION
Required flags: --output OUTPUT-FILE Use OUTPUT-FILE as the name of the executable to create Entry-point flags: --entry NAME Use the function identified by NAME as the executable's toplevel function. Called with SB-EXT:*POSIX-ARGV* as its only argument. If NAME has a colon, it is treated as a package separator, otherwise CL-USER is the implied package. --dispatched-entry DNAME Specify one possible entry function, depending on the name of the file that is used to start the application. The syntax of DNAME is APPLICATION-NAME/ENTRY-NAME. If the name used to start the executable matches APPLICATION-NAME, use ENTRY-NAME as the entry point. This can be used to choose one of many possible entry points by e.g. symlinking names to the application executable. If APPLICA- TION-NAME is empty, the specified ENTRY-NAME is used as a default if no other application names match. There may be any number of dispatched entry points, but only one default. Action flags: --load FILE Load FILE. CL:*PACKAGE* is bound to the CL-USER package before loading --load-system NAME Load an ASDF system identified by NAME --require NAME Use CL:REQUIRE to load NAME --eval CODE Use CL:EVAL to evaulate CODE. The code is read with CL:READ-FROM-STRING in the CL-USER package There may be any number of load/load-system/require/eval flags. Each is executed in command-line order before creating an executable. Load path flags: --load-path DIRECTORY When handling a --load, search DIRECTORY for files to load --asdf-path DIRECTORY When handling a --load-system, search DIRECTORY for ASDF system files to load --asdf-tree DIRECTORY When handling a --load-system, search DIRECTORY and all its subdirectories for ASDF system files to load There may be any number of load-path/asdf-path/asdf-tree flags. asdf-path arguments take precedence over asdf-tree arguments. Other flags: --help Show this usage message --logfile FILE Log compilation and load output to FILE --sbcl PATH-TO-SBCL Use PATH-TO-SBCL instead of the sbcl program found in your PATH environment variable For the latest documentation, see http://www.xach.com/lisp/buildapp/ buildapp 1.1 July 2010 BUILDAPP(1)
