Files of this type contain source code to be compiled by Apple IIgs native 
development environments.  This File Type Note obsoletes any publications 
bearing this information with earlier publication dates.
Changes since March 1990:  Added new vendor and language numbers and altered 
the warning about resource forks.
_____________________________________________________________________________

Files of type $B0 contain source code to be used by an Apple IIgs native 
development environment, such as APW.  The data fork of $B0 files contains 
straight ASCII text; nothing that should not be interpreted as ASCII should be 
in this kind of file.  The resource fork is reserved; it cannot be guaranteed 
that resources in these files are preserved by programming utilities.  The 
resource fork, if it exists, should contain Apple IIgs resources.

The auxiliary type of file type $B0 is used to distinguish between different 
compilers or assemblers.  The value in the auxiliary type is also referred to 
as the "APW Language Number," since APW matches language numbers with the 
auxiliary type of $B0 files to determine which compiler or assembler should be 
used to compile a source code file.  Throughout this Note, "APW Language 
Number" is used to mean "auxiliary type of file type $B0," even though a 
specific auxiliary type value may be assigned to a native development 
environment other than APW, and may, in fact, not represent an APW language.

Developer Technical Support assigns and catalogs all official APW language 
numbers, and effective May 1988, DTS has a new scheme for these numbers.  
Under the new scheme, the high byte of the APW language number is a vendor 
number and the low byte is a language number.  To form the APW language 
number, combine the vendor number with the language number.

Note:  Vendors who form their own language numbers in this fashion should 
       also inform Developer Technical Support of the new products to 
       ensure proper inclusion in future File Type Descriptors.

Following is a list of the APW languages which do not follow the new scheme; 
inclusion of a language on this list does not imply the language product 
exists or ever will exist under APW.

The following is a list of currently defined vendors and languages; inclusion 
of a vendor on this list does not imply the vendor is developing, or ever will 
be developing, any of the language products listed for APW.

    _________________________________________

The generic vendor names and language descriptions are more familiar in 
combination.  For example, an "Apple Resource Description" file would be Rez 
source code, and "Adobe Systems Page Description" is a Postscript(TM) file.

If, as a developer of native development software, you need a vendor number or 
a new language number for a language processor not currently covered on this 
list, write to the address in "About File Type Notes", to the attention of 
"APW Language Number Administration".

Note:  Language number assignments are considered provisional until the 
       applicant submits proof of publication of a language processor 
       using the assigned number.  Acceptable proof must include a 
       complete specification for the language that the processor 
       recognizes, as well as photocopies of public notices that discuss 
       the terms and details of publication (e.g., newspaper and magazine 
       ads, software reviews, brochures, circulars, electronic mail 
       solicitations, etc.).  Unless a developer has made prior 
       arrangements with Developer Technical Support, DTS may rescind a 
       provisional language number assignment after a period of one 
       calendar year from the date of assignment if a developer does not 
       submit the required proof of publication.
