This format is the output of the Paralax SPASM assembler (now defunct, I'm told). The file contains two columns of 16\[hy]bit hexadecimal coded values. The first column is the word address, the second column is the word data.

By default, SRecord treats this is big\[hy]endian data (the most significant byte first). If you want little endian order, use the -spasm\[hy]le argument instead.

Size Multiplier

In general, binary data will expand in sized by approximately 5.0 times when represented with this format (5.5 times in Windows).


Here is an example SPASM file. It contains the data \[lq]Hello, World[rq] to be loaded at bytes address 0x0100 (but remember, the file contents are word addressed).

0081 6C6C
0082 2C6F
0083 5720
0084 726F
