I had't seen that Cengage "book" before either. It reads like some first ye=
ar assistant professor's course notes converted into an ebook. The followin=
g statement in the book:

"The underscore character is not used in programmer-defined identifiers; it=
 is used in =93standard=94 Ada such as TEXT_IO.PUT(. . .). Occasionally, we=
=92ll use
single capital letters for identifiers in quick code fragments."

is just clueless and wrong.

I suggest that the OP look at the Ada Quality and Style Guide from one of t=
he sites below:
