Why this macro generate Error?


__________________________________________________________
I write this macro:
// Delete 3 chars at start of line for all except first line
// delete lines longer then 930 characters

textArea.goToBufferStart(false);
textArea.goToNextLine(false);

int textAreagetLineCount=textArea.getLineCount();
java.lang.String pos ="";

for(int j = 0; j < textAreagetLineCount; ++j)
{
textArea.goToNextCharacter(false);
textArea.goToNextCharacter(false);
textArea.goToNextCharacter(false);
textArea.deleteToStartOfLine();

textArea.goToStartOfLine(false);

if(textArea.getLineLength(j) >= 930)
{
textArea.deleteLine();

}
textArea.goToNextLine(false);
textArea.goToStartOfLine(false);
}
buffer.save(view,null,true);
jEdit.closeBuffer(view,buffer);
