if then statements with two conditions...?

Is it possible to setup two conditions for an if then statement in a pbash script?

For example, depending on the text value of a variable I parse out of an xml file, I want to assign it a numerical values.

Example:

Code:
if [ "$VAR" = "Upper" ]; then
VAR="25"
fi

if [ "$VAR" = "Lower" ]; then
VAR="25"
fi

Can these two statements be replaced with a single one?

VAR="25"
fi

What's "pbash"?

Code:
if [ "$VAR" = "Upper" ] || [ "$VAR" = "Lower" ]; then
  VAR=25
fi

Modern POSIX shells have a richer set of conditionals using [[ conditions ]], or you can use case:

Code:
case $VAR in Upper|Lower) VAR=25;; esac
