FX Program (FXP)

This format is a community format described and implemented by Bob Parish in 1996, along with a Microsoft Quick Basic program. It is also supported by CaS.

It can only contain an unnamed and unnumbered program, represented using the following grammar:

file = length LF *(byte LF) '0' LF

length = 1*%x30-39
byte = 1*%x30-39

The content is a CASIOLINK data part for a program, meaning:

• The first byte is : (0x3A);

• The last byte is the checksum of the second until the one before the checksum.

• The rest is the program.
