SERIN to BCD array on BS2

kelvin_koolohm

On a BS2, I have a 4 byte BCD array "INP_ARRAY" which shows up at B8, B9, B10, and B11
after an 8 byte array at origin.

If I use the "STR" special formatter in a "SERIN" command to load this array, will it refuse
to accept any bytes that are outside the range (20h - 7eh) (ASCII text)?
This would mean that BCD values for seconds, minutes, hours, and days-of-the-month
that were less than "20" wouldn't be accepted into the BCD array.

Is this my only choice:
knowing that the array is showing up at B8 thru B11,

SERIN RPin \FPin, baudmode, Timeout_Time, Timeout_Label, [B8,B9.B10,B11]

????

STR formatter does not refuse any bit strings. All 256 combinations are equally acceptable to it.

FWIW, using hard-wired register names is not typically done except for BS1. Assign names with VAR and let the IDE worry about where to put them.

Second question:
Can variable formatters be used on the LEFT side of an assignment?

I'd like to use the wasted high bit (B7) in ASCII character bytes to
signal my LCD display to "reverse-video" the ASCII character
associated with it.
Can I use the following code to set the B7 bit of the character byte?


ASKEE VAR BYTE
PTR VAR NIB
HIGHBIT VAR BIT

ASKEE = "A"
HIGHBIT = %1

ASKEE.BIT7 = HIGHBIT


More importantly, if the ASCII bytes are in a string array, can I use
the following code to individually set the B7 bits in the string?

ASKEE_ARRAY(PTR).BIT7 = HIGHBIT

Of course, the best way to determine if you can do something, is to try it.

That said, I could not get the buff(ptr).bit7 past the syntax checker. You can, of course, use buff(ptr) = buff(ptr) + $80
