I'm not sure if I understand you right, but I think the 'eval' builtin
could possibly help you:
#!/bin/sh
read a
while [ -n "$a" ];
do
eval "$a" # assigns 'data1' to 'var1', etc...
# getting the names of the variables:
tmp_var=$( echo "$a" | cut -d\= -f 1 )
# and the datas:
tmp_data=$( echo "$a" | cut -d\= -f 2 )
eval "$tmp_var=foobar" # does var1=foobar
read a
done
echo $var1 # should output "foobar"

I don't know what you intend to do with this, so I can't help you more,
HTH,
