Early approaches (most notably the [[UCSD p-System]] system) translated Pascal code into a machine-independent [[p-Code machine|p-Code]] representation. This intermediate code was then interpreted by a program specific to each architecture. As a consequence, only the small interpreter part had to be ported over to many architectures.

In the [[1980s]] [[Anders Hejlsberg]] wrote the Blue Label Pascal compiler for the [[Nascom|Nascom-2]]. Later he went to work for [[Borland]] and rewote his compiler to become ''[[Turbo Pascal]]'' for the [[IBM PC]]. This new compiler sold for $49, which was much cheaper than the price Hejlsberg originally asked for the Blue Label Pascal compiler.
