ARCH might already be defined.  In his case, ARCH is overridden only by
the provided parameter.

Not sure what you meant by your question, but if you're not familiar with
the '.' directive, cf. 'builtins' in sh(1).  If the script is not invoked
via '.' (a/k/a 'source' in bash), all the changes it makes are lost when
it exits.
