I have a script something like

DEFINE udf ..
DEFINE udf2 ..

IMPORT 'macros.pig'

rel = calltomacro('string',$keyparam);
rel2 = calltomacro('string2',$keyparam);
....
if I run this with pig -p keyparam=testparam --dryrun script.pig
 I get a valid script.pig.expanded created.

but if I run pig -p keyparam=testparam
grunt> run script.pig (or IMPORT 'pig.script';)

it fails with an error 'undefined param $keyparam'
why does this behave differently during --dryrun and inside grunt?

Thanks,
lauren

I did not know about the run command from inside grunt, but generally
speaking grunt does not yet support macros or parameters. I am eager
to get this fixed, myself.

The fix is-
grunt> run -param key=value script.pig
