Any question answered...

I'm trying to work out he value of a variable for a function in documentation I have found this.

Record length must be specified in the OPEN statement using RECL = bytes.

and

RECL = integer-value must be present for DIRECT files. It is the length in bytes of each record in the file. You will have to add up the KIND and LEN of all the items in a typical list.

I'm dealing with a single integer of kind 2 which apparently is 4 bytes, I can't find anything about LEN I presume this us just the length of the list so in my case 1*4. Or is there some other computer science this LEN thing could be?
