Well, I don't think he by "source" referred to source code, but rather 
to some site on the web where they can be downloaded.  I.e. he wanted 
some sorce for the source code... :-)

You wrote: "Applesoft and Integer BASIC aren't compiled" -- well they 
can be.  There were several Applesoft compilers, and at least two 
Integer Basic compilers.  Most Apple Basic programs weren't compiled 
though - at least not that much.  But they were usually not stored in 
ASCII form either, but in tokenized form.  Which means that the very 
first step of compilation - lexical analysis i.e. conversion of keywords 
and operators to tokens, was performed.  Integer Basic actually went one 
step further and did some parsing of the statements as well -- that's 
why e.g. unary minus and binary minus were represented by different 
tokens in an Integer Basic program.

Anyone who've tried to view a tokenized Applesoft or Integer Basic 
program directly, without first converting it to ASCII, know that they
need a little bit of "decompilation" before they become readable by 
humans.  The LIST command in the respective Basic interpreter does that.  
And so does your software CiderPress.
