You may know this already but some C= aware assemblers (eg 64tass)
natively understand the C= screen codes, so you can define strings in your
source which get translated at compile time, thus saving you the trouble.


.enc screen
my_message .null "abc1234"
.enc none

would compile to:

$01, $02, $03, $31, $32, $33, $34, $00
