Program

Syntax

PROGRAM ::= $\langle$COMMAND$\rangle$ | $\Lambda$

Static

A PROGRAM is statically correct as long as all its commands are correct in the global environment defined by the PROGRAM itself.

Run-time

A CoCoA5 PROGRAM is a (possibly empty) list of commands. A PROGRAM defines a global scope environment and loads all the packages from the cocoa/packages/ directory (no recursion on the filesystem!).

It also defines a $user package in which all the COMMANDs will be executed
