Example 1:
$$DD01 LIST RDW=3,IF=(1,EQ,C'A'),MOVE=(1,100,1)
Example 1 lists the first 100 bytes of all records of this variable-length dataset that contain the character A in the first data byte of the record (not including the 4-byte system RDW). The RDW is not included during record processing as specified by the RDW parameter and is not printed since the MOVE parameter is present with the LIST function.

RDW

Controls the inclusion or exclusion of the record descriptor word for variablelength
record processing. Must be the first parameter specified after a function.

RDW=n

Values for n are:
0 (Default) Include the RDW during record processing and display it on output.
1 Include the RDW during record processing, but do not display it on output.
2 Do not include the RDW during record processing, but display it on output.
3 Do not include the RDW during record processing, and do not display it on output

Personally, whenever a tool starts to impede rather than facilitate, I just use basic assembler language and all these annoyances usually disappear.
