I am using Ruby 1.86 to process a 7,000+ record file and using Regular Expressions to select and process content. To ensure that the Regexp are working correctly, I have been using “puts” to direct selected records to the console for examination. On examining the console output from the “puts” command I don’t seem to get all of the records being selected through the Regexp. My question is this: in using a simple ‘puts’ command, is there some argument that must be added to get every selected record to be displayed on the console output? And since I can associate each record in the 7,000+ file with a record count number, is there any reason to believe that the output to the console would not appear in the same sequence as the record numbers being encountered? ---

I am getting all of the records so it would seem that the program is OK. But experimenting further with the previous console output using puts, whenI remove the Regexp filtering component, I can see all 7,000 records flying by. As the other responder said, it must be the way that things get buffered. Why when I add the Regexp process the console output seems to get constrained is still a mystery. Thank you for your response. db
