Trouble is you will have to write your (non-trivial) annotation
processor in Java so it's a chicken and the egg problem.
For a brute force solution you could just create symlinks (shortcuts) to
your *.java files with *.jav extensions. Trial to write a PowerShell
script to do that.

Nice one. Thanks for that. I'll follow it up. Cheers.

You need to set up annotation processor files but I am not sure how to do this.
m:\javaprog>javac streamx.jav
error: Class names, 'streamx.jav', are only accepted if annotation processing
is explicitly requested

Subject: Re: How to change the default '.java' extension to '.jav'?
Thanks, but I can write, compile and run any Java program from SPF/PC (howbeit with some
'challenges') as long as it contains no "import" of classes etc.
All I wanted to know is how to change the default ".java" extension to a 3-char one e.g.
".jav", that's all. I can deal with the rest.
Thanks anyway.
Cheers, Chris Poncelet

I'm familiar with SPF/PC and that's great for simple editing with
something familiar from ISPF.
However, if you want to learn Java beyond "hello world" you will need
an IDE. Java is a complex language and just creating packages and
classes is onerous using a text editor. You need context assist and
one-click refactoring to help you and either IDEA or Eclipse will do
that.

SPF/PC is the CTC PC-version of ISPF/PDF. It supports Rexx (but not
the full IBM REXX), ISREDIT edit macros, primary and line commands,
tables, panels etc., and it also supports assembling, compiling,
link-editing and executing programs - all from within SPF/PC.
I use it for writing Rexx, C, C++, MASM 6.1 (the Microsoft version
of Intel assembler) and for just about everything else.
The problem with compiling Java is that SPF/PC supports only DOS
8.3 format files, which then excludes ".java" extensions as shown below:
javac C:\JAVA\MYPROGS\CH01\HELLO1~1.java >
C:\JAVA\OUTPUT\HELLO1~1.OUT
javac: file not found: C:\JAVA\MYPROGS\CH01\HELLO1~1.java
Usage: javac <options> <source files> use -help for a list of
possible options
The alternative would be to use "Notepad", up with which I will not
put.

Instead of these work arounds to use a prehistoric DOS-based editor
why don't you switch to an IDE?
The best IDE for Java is Intellij IDEA which has highly advanced
code analysis/refactoring features. What exactly does SPF/PC buy you?

No can do. The SPF/PC 4.0.7 editor is DOS-based, but has an

It's Windoze that needs fixing.

Thanks, but never mind.
The change to using '.jav' instead of '.java' for the compiler
would have to be done at Java's implementation level, i.e. as a
sysadmin or sysprog. I have found no-one among the Java
developers and course tutors who could tell me how to do this. So
I thought this list *might* know.
Better to fix the editor than to break the compiler.
