Joining 5 bit variables and splitting them into 8 bit ones later?

[richard]

why reading from a bit array from arbitrary position (not byte justified) returns garbage?

a minimal, complete and verifiable example MCVE

here is one that shows no problem at all pbp3, examination of lst file confirms reservation of the 4 bytes required for the bit array
if there was ever any doubt

Will take a look tomorrow...
Meanwhile, added decimal point, C and F sign support...
