Operation: (src) + (dst)
Condition Codes: Set on the byte result as in MOV
Description: Same as MOV instruction. The MOVB instruction in register mode
(unique among byte operations) extends the most significant bit of the byte
register (sign extension). Otherwise MOVB operates on bytes exactly as MOV
operates on words.

Condition Codes: Set on the byte result as in BIT
Description: Same as BIT.
The following subroutine scans a packed character string of variable length
lines, removes blanks and unpacks the string to left-justified length lines.
INSTRING is the address of the INput STRING, OUTSTRING is the address
of,the OUTput String. EOLCHAR. SPCHAR.‘and EORCHAR are the End Of
Line CHARacter, Space CHARacter, and End of Record CHARacter respec-
tively.
* See the note for the CMP instruction.
