Getting pyparsing.ParseException while reading .V21 file #178

Hi,

I am reading CWR file through this Data-api library. I am getting the following exception. I can send the file case by email if necessary.

Thanks for sharing, but the project is not being developed currently.

This project is very well designed. But It is difficult for me to understand all the details in a short time. I would like to ask some question if you like.

  1. Is there any limit on transaction num in one group？
  2. Under what conditions GRT is exoected？

@chopinx did you get a solution for the issue?
