Mr. Fix,

That is a SOS file extension, meant for use on an Apple III only. So it's a "no-go" on an Apple II of any kind. Here's the partial listing of ProDOS8 file extensions that reveals that info;

File Type Preferred Use
$00 Typeless file (SOS and ProDOS)
$01 Bad block file
$02 * Pascal code file
$03 * Pascal text file
$04 ASCII text file (SOS and ProDOS)
$05 * Pascal data file
$06 General binary file (SOS and ProDOS)
$07 * Font file
$08 Graphics screen file
$09 * Business BASIC program file
$0A * Business BASIC data file
$0B * Word Processor file
$0C * SOS system file
$0D,$0E * SOS reserved
$0F Directory file (SOS and ProDOS)
$10 * RPS data file
$11 * RPS index file
$12 * AppleFile discard file
$13 * AppleFile model file
$14 * AppleFile report format file
$15 * Screen Library file
$16-$18 * SOS reserved

You might mean S16 - which means it's a ProDOS 16 (which generally means GSOS) command. In that case you would need to boot into GSOS to run it.
