If there is a problem with the script, you might have had an error message after pushing the « Execute » button. Some of the error messages might point to a missing parenthesis, an unrecognized keyword or a variable being used before being defined. In this case, it’s easy to correct.

Sometimes, the error messages are cryptic or the program was running in an endless loop and you had to abort. In this case, Mastock offers two debug tools.

Step 1:

If you press the button « Analyze », you should see colors appear on the text. Each color has a signification, red is a keyword, blue a variable, yellow a numeric parameter, ….

Step 2:

When there is no typo, but more of a logic problem, you might want to dig deeper. In order to do that, press a second time on the « Analyze » button.

You should see a logical tree. Clicking on the arrows, open the next logical level and you can see how the various lines were logically interpreted.
