Hello Bill,
The Problem with Win95 Notepad is that it adds a .txt extension after you
save your sourcecode. So when you thought you saved it as HelloWorld.java,
you saved it as HelloWorld.java.txt. One option is to go into the MS-DOS
Prompt and type the following:
rename HelloWorld.java.txt HelloWorld.java
I personally think that the MS_DOS edit program is better for inputting the
source, rather than
Wordpad, Notepad, and Microsoft Word.
To get in to this program, Go to the Start Button of Windows 95, go to
Programs, then select MS-DOS. At the prompt type in,
edit <whatever your file is.with its extension>.
Let me know if this helps.
