Hi Matt, Going by the below example I have come across a senario which seems like a bug to me. Here is my dsl [condition][]{varname} is a Volume where {constraints}={varname} : RawVolumeTs ( where {constraints} ) [condition][]where {attr} is "{value}"={attr} == "{value}" [condition][]and {attr} is {value}=, {attr} == {value} Now, v1 is a Volume where status is "NV" and sourceId is 2 Translates to v1 : RawVolumeTs (status == "NV", sourceId == 2 ) Only when I put an extra space after and. Otherwise the ending quote of "NV" get cut-off resulting in v1 : RawVolumeTs (status == "NV, sourceId == 2 ) Also v1 is a Volume where status is "NV" and sourceId is 2 and volume is 1000 Give a totally incorrect drl v1 : RawVolumeTs (status == "NV", sourceId == 2 and volume is 1000 ) Thanks Pallav -----Original Message----- From: Shyam, Pallav (MSCIBARRA) Sent: Wednesday, September 03, 2008 11:55 PM To: 'Matt Geis' Subject: RE: [rules-users] Variable assignment in DSL Great. This is really exiting.

[condition][]{varname} is a Volume where {constraints} = {varname} : RawVolumeTs (where {constraints} ) That way, your DSL would read... rule "RT(2) against FT(32)" when V1 is a Volume where status is "NA" and sourceId is "ABC" V2 is a Volume where status is "NA" and sourceId is "XYZ" then end and the resulting DRL would read... rule "RT(2) against FT(32)" when V1 : RawVolumeTs (status == "NA", sourceId == "ABC") V2 : RawVolumeTs (status == "NA", sourceId == "XYZ") then End -------------------------------------------------------- NOTICE: If received in error, please destroy and notify sender.
