It is correct - I did lots of Turbo Pascal on a 2nd-hand original IBM PC wi= th two floppies. Since it was 4.7MHz it was a bit slower as described, but = later on 25MHz or more machines you needed a large project to notice a rebu= ild. The compilation was straightforward; the whole effort was on reducing = the build time. For instance a compiled unit resulted in a single .tpu file= with: the parsed declarations of the specification (called interface) and = the machine code of the body (called implementation). When you compiled fro= m the IDE it took source texts from the open editor windows instead of from= files to gain a bit of time (much, with floppies). For the fun of it, I've= included that latter feature in my LEA project ( https://sourceforge.net/p= rojects/l-e-a/ ) :-)
