p echo b export
d echo pi
d string 65535 const options(*varsize) varying

if %parms >= 2;
localTabs = tabs;

if %parms >= 3;

Yes you can have optional parameters...you'll have to check %parms() to

Refresh my memory (assuming it's something I actually knew at some

And how do I know whether they were passed?
