Shell Programming and Scripting
Dynamic Variable Declatation

Many thanks for the reply vgersh99.
In the last of my environment files I included your suggestion:
eval export \${MD_SYSTEM}_ZZ_EMAIL_SUPPORT="myname@domain.com"
Incidently, ${MD_SYSTEM} is established by another environment file prior.
In my scripts I updated the case statements where they are to be applied:
ZZ) EMAIL_WHO=${MD_SYSTEM}_ZZ_EMAIL_SUPPORT ;;
And hey-presto, a quick test of the script & I got my email.
You have just saved me a minimum 8-10 hrs of rewrites and amendments. And makes their application within future scripts high as this will allow me to write more generic scripts for the six environments we have here (1 script to be applied to each environment - sweet).
HUGE THANKS

vconsole.conf
VCONSOLE.CONF(5) vconsole.conf VCONSOLE.CONF(5) NAME
vconsole.conf - configuration file for the virtual console SYNOPSIS
/etc/vconsole.conf DESCRIPTION
The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font. The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported, allowing applications to read the file without implementing a shell compatible execution engine. Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=, vconsole.font.unimap= may be used to override the console settings at boot. Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only as fallback. OPTIONS
The following options are understood: KEYMAP=, KEYMAP_TOGGLE= Configures the key mapping table of for they keyboard. KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured a second toggle keymap and is by default unset. FONT=, FONT_MAP=, FONT_UNIMAP= Configures the console font, the console map and the unicode font map. FONT= defaults to latarcyrheb-sun16. EXAMPLE
Example 1. German keyboard and console /etc/vconsole.conf: KEYMAP=de-latin1 FONT=latarcyrheb-sun16 SEE ALSO
