ucblogo is the Berkeley interpreter for the Logo programming language.
|
|
|
|
Special features of this dialect are:
|
|
|
|
- Random-access arrays.
|
|
- Variable number of inputs to user-defined procedures.
|
|
- Mutators for list structure (dangerous).
|
|
- Pause on error, and other improvements to error handling.
|
|
- Comments and continuation lines; formatting is preserved when
|
|
procedure definitions are saved or edited.
|
|
- Terrapin-style tokenization (e.g., [2+3] is a list with one member)
|
|
but LCSI-style syntax (no special forms except TO). The best of both worlds.
|
|
- First-class instruction and expression templates.
|
|
- Macros.
