upper and lower case code

[dxs@evolving.com (Dan Stanger)]

i have a program where a function is called with mixed case symbols
for example
(f 'And 'Holdall)
clisp seems to upcase it.  it works correctly if i enclose it in bars.
(f '|And| '|Holdall|)
is there a way to have clisp recognize the case of symbols?
thanks,
