Generally, you don't get to do things quite that way.
Every program runs in a self-contained address space,
and communicates with other programs via files (this includes pipes
etc).
So what you need to do is use awk to compute and then print
the result you want. Observse:
| Following is the script i have written, but its not

[...]
| JVMMODE=""
| [...]
| while read myLine
| do
| echo $myLine|awk ' {if($0 ~/64/) {$'$JVMMODE'=-d64}} '
| done < $myFile
You want to do something like this:
awkout=`echo $myLine | awk '{if($0 ~/64/) {print "-d64"}}'`
[ -n "$awkout" ] && JVMMODE=$awkout
i.e. use the output of the awk script in a variable.
Also, since you're just looking for a "64" in the file,
you could write this:
JVMMODE=
if grep 64 "$myFile" >/dev/null
then JVMMODE=-d64
fi
instead of your while loop.
