Searching the table of contents of Pharo By Example I see "Using streams for file access" that would be a good place to start, and then browse other the methods of the classes used there, and also the "senders" of any of those that look interesting. cheers -ben On Sat, 25 Jul 2020 at 15:04, shawon58 <shawonhoque58@gmail.com> wrote:

Hello i am new in GUI in pharo . I am following Spec2 form where i can able to make form that send value and show in result tab. But my concern is i want to send the text field value to a Bat file which will execute a C++ file. So i want to use LibC system: 'a.bat textfieldinput' like this but how to do i dont know. If anyone have idea pleas share with me. In the screenshot u can see that i can send a number that shows in result tab. But now i want to send same number when i press submit than it will send to LibC system: 'a.bat textfieldinput' means in bat it will receive the number from the form.

Thanks
