I can only second this. I've never every been using sequence number to the last 
20 years. 

I can't believe what I just read about all the mangling being done on PARMDD 
content. When I code //XYZ DD *, I expect JES to return every single byte 
exactly as entered when the program is reading the data. Now, as I understand 
it, when coding PARMDD=XYZ, the initiator will mangle that data under complex 
rules instead of just concatenating all bytes into one single var-char field, 
leaving every byte as is. Hmm...

//    ....PRAMDD=XYZ
//*-+----1----+-- // 6----+----7----+----8
//XYZ DD *
SomeFirstLongParm // HereWithData=A1234567
,SomeSecondLongPa // HereWithData=01234567
,SomeThirdLongPar // HereWithData=B1234567

According to Peter's explanation, the initiator will recognize "standard 
numbering" on the second line and ignore those 8 characters. The program will 
get:

SomeFirstLongParm // HereWithData=A1234567,SomeSecondLongPa // 
HereWithData=,SomeThirdLongPar // HereWithData=B1234567

How quickly will one remember that "strip off if punch-card-numbering found" is 
in effect?
