Function
BCMP(068) compares the source data (S) to the 16 ranges defined by pairs of lower and upper limit
values in B through B+31. The first word in each pair (B+2n) provides the lower limit and the second
word (B+2n+1) provides the upper limit of range n (n = 0 to 15). If S is within any of these ranges
(inclusive of the upper and lower limits), the corresponding bit in R is turned ON. If S is out of any these
ranges, the corresponding bit in R is turned OFF.
Example Programming
When CIO 0.00 is ON in the following example, BCMP(068) compares the content of D100 with the 16
ranges defined in D200 through D231 and turns ON the corresponding bits in D300 when S is within the
range or OFF when S is not within the range.
For example, bit 00 of R is turned ON if S is
within the first range (B ≤ S ≤ B+1), bit 01 of R is
turned ON if S is within the second range (B+2
≤ S ≤ B+3), ..., and bit 15 of R is turned ON if S
is within the fifteenth range (B+30 ≤ S ≤ B+31).
All other bits in R are turned OFF.
Note An error will not occur if the lower limit is
greater than the upper limit, but 0 (not
within the range) will be output to the
corresponding bit of R.
