btw funny question:
isn't that dos syntax
set VAR="VAL"
echo %VAR%
?
anyway; csh or whatever. I recommend to write in batch-jobs
var1=/my/path
var2="\$var1=${var1}" # "" interpolates; escape with \
var3='var1 is stored in $var1' # '' does not interpolate: care the \ only
var4=`date` # store timestamp in var4 # assign output of command to var
echo "$0: starts $var4"
cd ${var1}/subpath
## etc.
means : whenever need to concatinate variables, write ${VAR}
but you can always write ${VAR} instead of $VAR fore readability.
