I am building a module to parse DTD content models and have a strange (to
me) problem on java DOS with the vertical bar character in the command
line. I am using W95, JDK1.02 and the DOS prompt window.

I type: 
java jumbo.sgml.ContentChunk (A|B)

using the 'vertical bar' character on my keyboard (the 'or' symbol in Java/C).
I assume this has decimal value 124 (from 'man ascii').

Under jview, this character is created with a value of 166.
Under java   it is created with a value of -90
If I quote the argument under java  (i.e. "(A|B)" ), I get a value of 65446
[corresponds to 2^16 - 90]

A - is this symptomatic of a general problem (e.g. something in Unicode).
B - how can I 'quote' a '|' symbol in the DOS commandline?


There is also a character 214 whose glyph seems to be a vertical bar with a
break in it. I assume this is unrelated to the problem (even though it is
what my keyboards display :-)
