Re: Retreive Source an MI program

Dear Sirs,
The background is :
I have many Program on ILE (RPGLE,CLE ) and MI  , but we have no program
source .Last time when we want to change the logic program we just ask the
seller, but unfortunetly now the seller are not exist anymore ( "Out of
Bussiness") .
A year ago I already contact to source retrieval but unfortunately  they
didn't have decompiler for ILE
Regards,
Sas
