Defining PostScript /DataSource from decimal values

I have the following decimal numbers: 61440 3840 240 65280 4080 1088 2176 8432

I need to define a /DataSource and need the following output:

/LogFunctionDict 10 dict def LogFunctionDict begin
 /logdatasource {/DataSource < f000 0f00 00f0 ff00 0ff0 0440 0880 20f0 > } def
end

I cannot figure out how to get the decimal numbers into the /DataSou开发者_运维问答rce < .. > without error.

Any ideas?
