[SunHELP] source'ing and $1

[Adrian.Florea at alcatel.ro]

Hi,

When you launch the script check for a env var (e.g. MY_FIRST_ARG).
If is set to something (e.g. not empty) then proceed with this as
argument.
When you'll run the script with $1=1 you'll do a export for this env var
with a specified value (in this case 1) and after that you'll find here
the value for subsequent calls. ...


maybe it helps...
