   I worked for a company which was (well, *is*, but going down fast) fond of
making everything proprietary (i.e. non-standard).  They came up with a 
language called DASL (*), based very strongly on C, which
actually perverted the meaning of arithmetic in such a way that 
"argv = argv + n" ACTUALLY MEANT "argv = argv + n*sizeof(argv *)" !!  That
wasn't documented anywhere, and we had one hell of a time with a certain 
piece of code until we figured out what was going on.
   For the record, I think the "++var" idiom is vastly preferable to making up
yet another idiom.

* DASL is a registered to Datapoint Corporation to denote their proprietary
  programming language.  And if I never see another DASL program in my life
  I'll die happy.
