Word processing
with the ASSIGN
command
Syntax: = (STORE)
Operands: B, W, D
Action:
Assign the content of the word accumulator to the addressed operand. Unlike
bit execution, in word processing you can also use the = command within a
sequence of word-gating operations. This command can be used several
times in succession.
Example:
Gate a constant and byte B5 with AND, and assign the result to byte B8 and
byte B10.
Initial state:
Constant 54 = 36 (hex)
Byte B5 = 2A (hex)
Byte B8 = ?
Byte B10 = ?
Function STL Accumulator contents [bit] Operand contents [bit]
31..15 ..................... 7 ................. 0 7 ............ 0
Load the constant
into the word
accumulator.
L K+54 0 ..... 0 000000000110110
Assign the contents
of the word
accumulator to byte
B8.
= B8 0 ..... 0 000000000110110 00110110
Gate the contents of
word accumulator
and byte B5 with
AND.
A B5 0 ..... 0 000000000100010 00101010
Assign the gating
result to byte B8.
= B8 0 ..... 0 000000000100010 00100010
Assign the gating
result to byte B10.
= B10 0 ..... 0 000000000100010 00100010
