I use Turbo Pascal extensively, such that I develop large programs comprised
of many modules (or Units).  It was always difficult to trace through a
program, not knowing in which file a particular Procedure or Function was
defined.  Then one day it dawned on me, while perusing my MKS Toolkit
manual, that they had a program, called ctags, that is used to create a
"tags" file which contains all of the functions in your C programs, and 
which the editor vi can use to jump to the appropriate place in the proper
file.  So I ran it on a C program, determined what the "tags" file format
was like, and then quickly created a ksh script to build a similar file of 
Pascal Procedure and Function references.  Now, within vi, I simply place my
cursor on the name of a Procedure/Function, press ^], and it immediately
loads in the proper file and jumps to the location of the Procedure/Function.
(And, with vi, it is easy to return to the file and location I was at 
previously by the :e# command.)  Wow!  This has really saved me a lot of
time and trouble.  (I am so VERY greatful, at times like this, for the
great power in a lot of UN*X tools, and the wonderful implementation that
MKS has done!)
