Alpheus AFP Parser is a library and parser for the IBM Advanced Function Presentation (AFP) document/print stream format. Alpheus covers all AFP specifications: MO:DCA, BCOCA, CMOCA, FOCA, GOCA, IOCA, and PTOCA. It is a complete implementation. Every Structured Field, Repeating Group, and Triplet is fully implemented as Java class. Alpheus AFP Parser was written from scratch and has no external dependencies.

 * Programming Guide and Line Data Reference(ha3l3r04.pdf), page 92.
 
 The Fixed Data Text
 * structured field contains text that can be selected and presented with LND, RCD or XMD structured
 * fields in the Page Definition. This text is used when flag bit 7 of the LND, RCD or XMD is set to
 * B'1'. Any number of FDX structured fields can appear, but the total number of data bytes must
 * match bytes 0–1 of the Fixed Data Size (FDS) structured field. The output should fit on the page,
 * and the fit can be affected by the size of the font used.
