Programming with Ch (ChIDE)

Q:  I type a Ch program in Google Docs first. I get syntax errors on the quotation marks when I copy and paste the  program from Google Doc into ChIDE. How can I fix this?
A: Google Docs uses a different symbol for quotation marks that ChIDE does not recognize. Google offers a free plugin called Text that can be downloaded and used to write Ch programs in. If you write a program using Text and save it as a .ch file, you will not have syntax errors when opening the program in ChIDE.

Q:  How do I access and use the abbreviations in ChIDE?
A: To access the abbreviations files from ChIDE, click on the “Options” button at the top of the window, and select “Open ChIDE Global Abbreviations File”, or “Open ChIDE User Abbreviations File”. For a description of the Global and User abbreviations and how to use them, open the ChIDE Users Guide (found in the Documentation section of C-STEM Studio), and go to section 3.7.

Q: Why can’t I launch ChIDE?
A: It is likely that the license for your machine is expired. Try launching Ch Command Shell, as it will display an error message if your license is expired. Ch Command Shell can be found in C-STEM Studio; it can also be found on your desktop (Windows) or your dock (Mac), as the red “Ch” icon. If this is the case, you can contact SoftIntegration at support@softintegration.com for license questions.
