That sets up a bash-local variable. If you want it to be exported to
the environment visible to child processes, then you _also_ need to use
export, as in either:
VAR=blah
export VAR
or
export VAR=blah
However, VAR is not seen in env in /path/programtorun.sh (called from cron).
Right - bash maintains two sets of variables, and only the exported ones
are visible to children.
