CHAPTER 14 USING MACROS
14.4.2. Data Transfer
Assignment ( = )
Format P1 = P2 Data Type U/S/UD/SD/F/B
Function Assigns the value of P2 to P1.
P1 (I/E) The destination.
P2 (I/E/C/AE) The source.
Example 1 $U2 = 123.45 (F) /* Assign 123.45 to $U2 (and $U3) */
Example 2 $U100.f = 1 (B) /* Turn on the specified bit */
Example 3 W60 = ( $U30 + $W50 - 1000 ) / 2 (SD) /* Write the result of the arithmetic expression to W60. */
Example 4 V0.0 = 2\M0 (B) /* Assign the bit value of M0 of link 2 to the bit V0.0 of link 1*/
Logical NOT ( = ! )
Format P1 = ! P2 Data Type B
Function Reverses P2 and saves the result in P1.
P1 (I/E) The location to save the result.
P2 (I/E) The operand.
Example 1 $U2.3 = ! $U3.4 (B) /* If $U3.4 is 1 (On), $U2.3 is 0 (Off) */
" "
Format P1 = "P2"
Function Copies the quoted ASCII character string P2 to P1. Note that the string is a null terminated string.
If the length of the string is N then N+1 bytes will be copied to P1 and the last byte is 0.
P1 (I) The location to save the result.
P2 (A) The quoted ASCII character string.
Example 1 $U60 = "TEST" /* The null character (00h) will be moved to the low byte of $U62 */
Example 2 $U20 = "ABCDE" /* The null character (00h) will be moved to the high byte of $U22 */
MOV
Format P1 = MOV(P2,P3) Data Type U
Function
Copies P3 words of P2 to P1.
P1 (I/E) The starting location of the memory to receive the copy.
P2 (I/E) The starting location of the memory to be copied.
P3 (I/C) The number of words to be copied.
Example 1 $U100 = MOV( $U200 , 16 ) /* Copy the 16 words starting from $U200 to $U100 */
Example 2 W60 = MOV( $U200 , $U2 ) /* Copy the word array starting from $U200 with the size specified in
$U2 to W60.*/
Example 3 $U10 = MOV ( 2\D100 , 10 ) /* Copy D100 ~ D109 of link 2 to $U10 ~ $U19.*/
