Hi Chris,

the Keil or the free Metalink 8051 assembler support high and low expressions, e.g.:

mov r0, #high(1234h)
mov r1, #low(1234h)


Try one of these, they are Intel compatible and assemble also the Atmel, Dallas, Philips aplication notes.

Avoid assemblers with dot expressions, e.g. ".ORG". Since this is not Intel syntax like and you can not reuse code examples from application notes.
