Evaluation

In order to evaluate programs that the user has implemented,

• The text of the program is in a text% object, available from the definitions-text instance variable of the drscheme:unit:frame% class.
• Use @flink drscheme:basis:process/zodiac to process the text of the program.
• For evaluation, use the function @flink basis:initialize-parameters .
• Syntax errors are handled by raising a exn:syntax exceptionof the MzScheme manualmz:exns.
