Well, if you are forced (as I was a year or two ago) to use C on big
IBM iron (3090 running VM/CMS) you find yourself more or less forced
into using trigraphs. A large number of the characters which are
important to C {}[]| and probably a few I've forgotten are not,
pragmatically, useable, because the EBCDIC codes for them are not well
defined. (There are somthing like 9 possible 8-bit values for each of
these chars, which in some cases overlap -- i.e. [ in one encoding will
be the same as ] in another. Different sub-models of 3270 keyboards
use different encodings, and different programs ditto.
