Jim,

If you ever write some sort of parsing routine, you'll understand the
problem.  When some character has a special meaning, like the quote as
string delimiter, (or the backslash in C, or '<' and '>' in HTML), you can't
use that character normally in a string.  If you need to use that character
in its 'normal' sense, you have to have some way of 'escaping' the parsing.
In RPG and CL you have to use two quotes when you want to have a quote in a
string, just like you have to use '\\' in C if you want a backslash in a
string.  But it can get very ugly if the string has to pass through a few
interpretation layers (try to build a command string in RPG for OPNQRYF with
some concatenation for the QRYSLT parameter).
