[Nottingham] A quick bourne shell scripting question

[Michael Erskine]

Hi,

Here's a query for any shell scripting folks...

I have a list of variables I'd like to echo to STDOUT so I have a loop
thus...

for var in VAR1 VAR2 VAR3 VAR4
do
    echo "${var}=3D${${var}}"
done

...but it doesn't work -- how can I get the desired result?

BTW: the shell in use is ash as provided by BusyBox 0.60.5.

Regards,

Michael.
