I did get one thing out of that... I need to create a macro to
define the mask flags -- since they use an unexpected equate format. I
created my definition macro to generate either relative mask flags (that
have an unnamed base location assuming an immediately prior 1-byte flag
field definition) or absolute mask flags (that have a named base location
allowing for a multi-byte flag field definition using BASE+0, BASE+1,
BASE+2, etc.). Thanks.
MACRO
&FLAG DF &MASK,&BASE,&BAD DEFINE FLAG BIT(s)
