Example 1
SUBSET FROM(IN1) TO(OUT1) REMOVE INPUT HEADER TRAILER
This example shows how you can remove the header record (first record) and trailer record (last record).
The variable-length input records look like this:
Len|Data
33|01A RODENTS FFFFF
23|01A VOLE BINKY
26|02B HAMSTER GARFIELD
22|03A RAT JUNE
24|04B MOUSE MICKEY
21|01A COUNT 004
We just want to keep the data records. We use REMOVE, INPUT, HEADER and TRAILER to indicate we want to remove the header and trailer input records.
The output records would look like this:
23|01A VOLE BINKY
26|02B HAMSTER GARFIELD
22|03A RAT JUNE
24|04B MOUSE MICKEY
Note that we could use FIRST and LAST instead of HEADER and TRAILER.
