Syntaxes Interpreted by APT Import

The purpose of the APT Import is to store a tool path created from parameters included in the imported APT file.

Listed below are the syntaxes interpreted by APT Import for enriching the stored tool path. Syntaxes that do not include recognized parameters are stored as is in the tool path and are generated as is in the APT file (for example, this is the case for PP words and comments).
