Depends upon the environment. Under AmigaOS you
have RawDoFmt(), which is
part of Exec and available to Assembly language programmers (and it works
similar to C's printf()). Under MS-DOS you have INT 21h, funtion 9, which
prints a text string (ended by a `$'). But all you really need is a way to
print out characters, leaving printing of numeric values as a programming
exercise.
Besides, why not steal such stuff from BASIC ROM? On the C64, print a string
from memory by setting A/Y to the localtion and jsr
$ab1e, and use the routine
at $bdcd that LIST uses to print line numbers for 16-bit
unsigned int.
