Each record has a RECLEN field which specifies the number of bytes of information or data which follows the
RECTYP field of the record. Note that one data byte is represented by two ASCII characters. The maximum
value of the RECLEN field is hexadecimal ’FF’ or 255.

Each record has a LOAD OFFSET field which specifies the 16-bit starting load offset of the data bytes, therefore
this field is only used for Data Records. In other records where this field is not used, it should be coded as four
ASCII zero characters (’0000’ or 03030303OH).
