ASCII Compare (CMPV)
The ASCII Compare instruction compares two groups of V–memory registers. The CMPV
will compare any data type (ASCII to ASCII, BCD to BCD, etc.) of one series (group) of
V–memory registers to another series of V–memory registers for a specified byte length.
“Compare from” Starting Address:
specifies the begining V–memory register
of the first group of V–memory registers
to be compared from.
“Compare to” Starting Address:
specifies the begining V–memory register
of the second group of V–memory
registers to be compared to.
Number of Bytes: specifies the length of
each V–memory group to be compared
SP61 = 1 (ON), the result is equal
SP61 = 0 (OFF), the result is not equal
CMPV Example
The CMPV instruction executes when the AIN instruction is complete. If the compared
V–memory tables are equal, SP61 will turn ON.
