Adds 5 to the PLC memory address in IR0 to
move to the beginning of the next record.
Defines record table 1 with 1,000 records of
5 words each.
Stores the PLC memory address of table
number 1's first record (record 0) in IR0.
Jumps past the FOR-NEXT loop if the pro-
cessing conditions haven't been set.
Controls the FOR-NEXT loop for a maximum
of 1,000 repetitions (1,000 records).
Compares the contents of word 1 to #1234,
word 3 to #ABCD, and word 5 to #9999.
If words 1, 3, and 5 contain the comparison
data, the record number is stored in D00000
and BREAK interrupts the loop.
Returns execution to FOR to continue the loop.
Jump destination if the processing conditions
haven't been set.
Increments IR0 by five with each repetition and compares the first, third,
and fifth words in each record to the comparison data. Writes the record
number to D00000 and breaks the loop if matching data is found.
