{{Blockquote|The full name of the compiler is "Compiler Language With No Pronounceable Acronym", which is, for obvious reasons, abbreviated "INTERCAL".}}

The original Princeton implementation used [[punched card]]s and the [[EBCDIC]] character set. To allow INTERCAL to run on computers using [[ASCII]], substitutions for two characters had to be made: <code>$</code> substituted for <code>¢</code> as the ''mingle'' operator, "represent[ing] the increasing cost of software in relation to hardware", and <code>?</code> was substituted for <code>⊻</code> as the unary [[exclusive-or]] operator to "correctly express the average person's reaction on first encountering exclusive-or".<ref name="manual72"/> In recent versions of C-INTERCAL, the older operators are supported as alternatives; INTERCAL programs may now be encoded in [[ASCII]], [[Latin-1]], or [[UTF-8]].<ref>{{cite web|url=http://c.intercal.org.uk/manual/atvm81sp.htm|archive-url=https://archive.today/20121224065530/http://c.intercal.org.uk/manual/atvm81sp.htm|url-status=dead|archive-date=2012-12-24|title=Princeton and Atari Syntax – C-INTERCAL 0.27 Revamped Instruction Manual|access-date=2012-11-12}}</ref>
