declaimed the following:


>What I don't understand is, why didn't the same issue apply to Pascal?

	Jensen&Wirth Pascal did not have "include/import" or any other
capability for separate files... Every program was contained within a
single source file; every compilation compiled the entire program.

	I don't recall if UCSD Pascal allowed for separate compilation (some
Googling indicates it did). Alcor Pascal (another p-code type
implementation; sold as TRS-80 Pascal by RatShack) used text files (hex
representation) for object files, and one /could/ use a text editor to
extract functions and build up a new code module from parts. 

	Heck -- Google results show that the concept of separate compilation
for Pascal was worthy of research papers at both ACM and IEEE around 1980.
