Another difference between ASCII and EBCDIC which can throw off some
programs:  in ASCII, upper case characters are lower values than lower case.
In EBCDIC, they are larger.  The pattern of code assignment is such that
various shortcut tricks differ even in availability.  EBCDIC text can be
shifted to upper case by just ORing X'40' (a blank) with other characters
(it will modify control characters, but these usually don't get past a
terminal controller).
