There are two Focus on Data process statements:
- NFOCUS
- Focus applies to the new file
- OFOCUS
- Focus applies to the old file
These two statements select (or
"focus on") rows or columns
of data to be compared. In other words, only these rows or columns
are considered when performing the comparison (or search) process
and all other rows or columns are ignored. Up to 254
"focus" statements
can be entered for each file.
Notes: - NFOCUS and OFOCUS statements are mutually exclusive to NEXCLUDE
and OEXCLUDE statements if using the same operand keyword (ROWS or
COLS).
- Do not use the NFOCUS or OFOCUS process statement if the Y2DTONLY
process statement has been specified.
Compare Types: FILE (ROWS option only) and LINE
>>-+-NFOCUS-+--+-ROWS-+--start_position--:--end_position-------><
'-OFOCUS-' '-COLS-'
- start_position
- If
ROWS operand used, the first row (record) to be selected for the comparison.
If COLS operand used, the first column to be selected for the comparison.
- end_position
- If ROWS operand used, the
last row (record) to be selected for the comparison. If COLS operand
used, the last column to be selected for the comparison. (Must be
separated from the start_position by a colon.)
