Hello Boris,

Thanks for the help. Unfortunately I'm still having problems.

Below is the latest code I've attempted in a workspace.
I get this error:
StandardFileStream(Object)>>error:
error: aString
	"Throw a generic Error exception."
	^Error new signal: aString

"Concatenate 2 Wave Files"
| fileDir wave1 wave2 wave3 file1 file2 file3 |
fileDir := FileDirectory on: 'C:\Documents and Settings\Jimmie\My 
Documents\My Music\MP3\Alexander Scourby\waves'.
file1 := fileDir fullName, '\Genesis 37a.wav'.
file2 := fileDir fullName, '\Genesis 37b.wav'.
file3 := fileDir fullName, '\Genesis 37k.wav'.
  wave1 := (StandardFileStream fileNamed: file1) binary.
  wave1 := ReadStream on: wave1 contentsOfEntireFile.
  wave2 := (StandardFileStream fileNamed: file2) binary.
  wave2 := ReadStream on: wave2 contentsOfEntireFile.
  wave3 := (StandardFileStream fileNamed: file3) binary.
  wave3 nextPutAll: wave1.
  wave3 nextPutAll: wave2.
  wave3 flush.
  wave3 close.
  wave2 close.
  wave1 close.

I've browsed the WAV code. I don't understand most of it. I've browsed 
lots of code to find examples of writing binary data to files. I haven't 
succeded in learning yet. I don't know what I'm missing.

I've banged my head on this for a few hours browsing code trying to learn.

I'm no Python expert but in less that 5 minutes I did the below and was 
successful at accomplishing my task.

I am very pro Squeak. It is frustrating that I was able to accomplish 
this so easily in Python, but have heretofore failed in Squeak. :(

Anybody know where I'm failing above?

Thanks,

Jimmie Houchin
