Experts messages, how to save them ?

[LAS TEN]

Hello,

Newbie question:

I have an expert that output some messages (with Print()). I let it run more time and I observed that the outputs in Message Terminal are not saved in log file. I also observed that this output is, I think, fixed number of lines or storage space as older messages disappear from this window.

So; how can I increase this output ?.

If is not possible how can I save in a file those messages ?

Thanks in advance for replies!

Print/Alert messages are always saved in the log file, there is no maximum.

In the Experts tab, right click -> open. That will flush cached messages to the file, and open Explorer to that directory. Open the file.

You could always go old-school and save the messages in a log file of your own creation.

See the example code at the bottom of this documentation page:
