How can I pass command-line parameters with whitespace to an apache pig script?

[Abhijit Chanda]

Hi,

I want to pass a filter statement with in my pig script using parameter
substitution.

For that I have tried
           exec -param flt='a1==1 AND a2=2' filterscript.pig

But sadly it is throwing an exception message
           ERROR org.apache.pig.tools.grunt.Grunt - ERROR 101: Local file
'AND' does not exist.

Pig version - 0.9.2

Any help will be appreciated
