Maybe. It depends on the employment policies of the big drug outlet
that you work for: CVS, RiteAid, WalMart, Target, etc.
Pharmacists are becoming a dime a dozen and the big drug outlets have
pretty much put the local mom/pop pharmacy out of business.
When you work for one of the big outlets, you're just another

That's what my brother learned on when he was doing his civil
engineering tech course at Conestoga College a couple years later -
they switched to WatFive while he was there. They had a Honeywell at
the college that basically never worked (they refered to it as the
"honey wagon" computer.

A couple of years later, when I had to take the same courses for credit, we
used WatFIV (no 'e'). WatFIV == WATerloo Fortran IV.
In the EE department, we had a couple of Bendix G-20s pulled out of the scrap.
Fortunately I never had to use them (avoided those courses). I did a lot of
work on the analog computers, though. I was the only one who did.

It was fortran 4 (language) with the waterloo compiler 4 in Fortran
IV with WatFor, and Fortran 4 (language) with waterloo compiler 5 in
Fortran IV with WatFiv, or watfive, or wat5. All were used.
The language was Fortran (for formula translator) and the compiler was
a separate program. Fortran is a compiled language, like C, not a
The same code could be compiled to work on different processors and
operating systems just by feeding the code into the proper compiler.

Hence "ForTran", not "Fortran" (as in "BASIC", not "Basic"). It is a
translated language, the compiler translates from ForTran into assembler. The
assembler output was just a JCL statement away. WatFour/FIV also had a /CLG
option, to Compile, Link, and Go, sorta-kinda like an interpreter to the user.
BASIC is (classically) an interpreted language. A compiler is a translator
(translates the HLL into another language, often machine). An interpreter
does a statement at a time.
Sure, as with all compiled languages. A compiler that runs on one computer
and produces code for another is called a "cross-compiler". Of course that

Found it, and a $12 item would cost $78 today. Still, with a slide rule,
you had to have an idea of what the answer would be, as they did not provide
decimal places in most cases, unless the value was less than one on the
scale. Interpolation was key.
For other uses, see Interpolation (disambiguation).
In the mathematical subfield of numerical analysis, interpolation is a
method of constructing new data points within the range of a discrete set of
known data points.
In engineering and science one often has a number of data points, as
obtained by sampling or experimentation, and tries to construct a function
which closely fits those data points. This is called curve fitting or
regression analysis. Interpolation is a specific case of curve fitting, in
which the function must go exactly through the data points.
A different problem which is closely related to interpolation is the
approximation of a complicated function by a simple function. Suppose we
know the function but it is too complex to evaluate efficiently. Then we
could pick a few known data points from the complicated function, creating a
lookup table, and try to interpolate those data points to construct a
simpler function. Of course, when using the simple function to calculate new
data points we usually do not receive the same result as when using the
original function, but depending on the problem domain and the interpolation
method used the gain in simplicity might offset the error.
It should be mentioned that there is another very different kind of
interpolation in mathematics, namely the "interpolation of operators". The
classical results about interpolation of operators are the Riesz-Thorin
theorem and the Marcinkiewicz theorem. There are also many other subsequent
One got used to keeping track of decimal places in one's head, a skill I
quickly lost when switching to a calculator. Even though I do such
calculations every day, I can't even do the simple estimates anymore. A
calculator is just too handy of a crutch to retain that skill.
It's not so much interpolation as estimation and that's only needed to read
the final result (or add ;-).

If you're a smoker, blame your government. Tobacco is incredibly cheap;
taxes, not so much.
