No, Enrico's example is straight from the DFSort Tricks. It causes sort to read as many records as needed to fill the output LRECL (TOLEN), concatenate them together and write them out as one record. In fact, from the DFSort Tricks manual:
Here's a DFSORT/ICETOOL job to combine each group of 3 records into one long record.
//COMB1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN1 DD DSN=... input file (FB/10)
//OUT1 DD DSN=... output file (FB/30)
//TOOLIN DD *
RESIZE FROM(IN1) TO(OUT1) TOLEN(30)
TOLEN(30) indicates an output length of 30. RESIZE automatically resizes each group of 10-byte input records to
a 30-byte output record.
All you need to know to use RESIZE is the input length and the desired output length
The problem I have is that people can explain things quickly but I can only comprehend slowly.
