True, and before units in Turbo Pascal(*) and Modules in Extended 
Pascal, nothing was standardized about breaking up the source into 
multiple parts.

Most dialects either adopted some form of C "extern" like handling, and 
the more advanced ones some form of Modula2 derived modules, either 
directly, or via the lengthy Extended Pascal standardization process.

(*) Turbo Pascal was strictly not a standard, but influential enough to 
set one.
