In BASH and KSH you can do things like:

Code:
VARNAME="$proc$val"
echo "value of ${VARNAME} is ${!VARNAME}"

Also, you can avoid the eval by feeding the variable name into read:

Code:
... | read "$proc$val"

Note that this won't work right in other shells, because the 'read' will end up in a subshell. KSH orders pipes in reverse for this reason.

ipescript

IPESCRIPT(1)						      General Commands Manual						      IPESCRIPT(1)

NAME

       ipescript - Run an Ipe script (written in Lua)

SYNOPSIS

       ipescript script { arguments }

DESCRIPTION

       ipescript  runs	an Ipe script written in Lua.  The Ipe bindings are automatically available in the script.  Ipescript looks for the script
       in any of the script directories.

       The script argument should not contain the .lua extension.

ENVIRONMENT VARIABLES

       ipescript respects the following environment variables:

       IPELATEXDIR
	      the directory where ipetoipe runs Pdflatex.

       IPESCRIPTS a list of directories where Ipescript will look for
	      scripts.	When this variable is not set, Ipe searches first the current directory, then ~/.ipe/scripts, and finally the  system-wide
	      Ipe script directory.  When this variable is set, it should contain a list of directories, separated by semicolons.  A single under-
	      score is replaced by the system-wide Ipe script directory.

       IPEDEBUG
	      set this to 1 for debugging output from ipescript.
