User Program Files
Ir-Transfer Utility C DLL regards MS-DOS files with the extension .PD3 as user program files
(object program files). Files are developed using the PDT 1100-BASIC 3.0 Compiler.
As shown, each record in a user program file is fixed to 128 bytes in length (except the last
record) and suffixed by a set of CR and LF codes (CR-LF codes), 0Dh and 0Ah.
