Still can't understant this language! [message #12343]

Hello again,

I'm stuck again with IDL (version 4). Having bought David's book, I discovered
my data was different to his, so I thought I'd have az quick look through the
data to see which sets were which. I thought this would do it:

for i=0, 50 do begin &$
print, i &$
test_val=loaddata(i) &$
help, test_val &$
endfor

(entered at the command line)
instead I get stuck in an infinite loop which effectively trashed the session.

this _does_ work, however:

for i=0, 50 do begin &$
print, i &$
j=i &$
test_val=loaddata(j) &$
help, testval &$
endfor

anyone have any ideas why?

Thanks,

martin
