shiftout help

I am working on a little dot matrix project and i need a little help
with the shiftout command. the chips (10 of them) that i am using are
the Toshiba TB62713F. I am going to dasy chain them. but i am haveing
a little problem with HEX and variables in the same output data. The
IC's recive a 16 bit word well the first 8 bits are a constant ($21)
then the last 8 bits are the variable (ASCII code
[noparse][[/noparse]0=$30,1=$31,A=$41,a=$61]). How do I get it to work?
also, how could I split up a DEC variable (1,234) so I can send it to
the IC's
IC1 would see $21 then the number "1" ($31)
IC2 would see $21 then the number "2" ($32)
IC3 would see $21 then the number "3" ($33)
IC4 would see $21 then the number "4" ($34)
The IC's that I am using has a ROM inside that has the ASCII code
built in.
Thanks,
TC
