U2, U4 Specifies unsigned decimal format. Data length of 2 or 4 bytes is consumed. F4, F8 Specifies floating point of 4 or 8 bytes. G m.n Specifies that the data pointer should be positioned m bytes and n bits into the data. O m.n Omits, from the current location of the data pointer, the next m bytes and n bits.
R m Reverses the data pointer m bytes.
Some macros are provided that can be used as format fields to quickly access data. The data pointer is not moved. The data accessed by a macro is hexadecimal by default. This macro causes data word 1 to be accessed but to be considered as 2 bytes and 3 bits of binary data.
