First of all: Thanks! ☺ My binary data specification is: Header: 512Bytes; Field1: 21504 bytes (21KB); Field2: 5Bytes; Field3: 1Byte; Field4: 3 Bytes <--Stating at byte 316 counting from the beginning of the file. This means that Field4 is placed inside the Header field. “leadingSkipBytes” or “alignment” would do, but can you specify the place you start counting? Thanks.

I have a binary file specification that specifies some fields referenced by the beginning of the binary info. For instance imagine that there is a field with 1024Bytes and the next one starts at byte 512 counting from the beginning of the info. Is it possible to do that using dfdl? I’ve seen dfdl:floating, but I can’t find much info on that. Thanks.
