Oops, I didn't check this properly. I just looked at the above & thought it
was about right, but IDL has been fooling me:

I thought the string+''x syntax ought to work (why doesn't it?) but it doesn't,
it just doesn't always generate an error message. Oh dear. In fact:

wmc> h_string='10' & h_long = long(h_string+''x) & print,h_long
-2596734
wmc> h_string='10' & h_long = long(h_string+''xl) & print,h_long

h_string='10' & h_long = long(h_string+'
^
% Long integer constant must be less than 2147483648.

I'm confused..., but I suspect IDL is too...
