How to Migrate Old ERTS Scripts

ERTS for Cognition Lab is a new implementation of the original ERTS Scripting Language for DOS. For anyone familiar with the original DOS-based version, the new implementation will look and feel like the original standard.

However, there are some minor differences, both syntactical and conceptual, which will make old scripts run only after minor adjustments. Those differences are due to differences in the technology stack (e.g. HTML5 canvas vs. direct access to VGA graphics card with color palette mode), and some design decisions to further simplify the language.

To help you understand the differences and adjusting old ERTS scripts, this chapter lists some of the differences and new capabilities which did not exist in the original DOS-based implementation. Please note that this list is not complete. In case of syntax errors, please read the reference manual.
