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 drscheme:basis:process/zodiac to process the text of the program.
• For evaluation, use the function drscheme:basis:initialize-parameters.
• Syntax errors are handled by raising a exn:syntax mz:exnsexception, see section of the MzScheme manual.
