I have Jdeveloper with version 220.127.116.11.0 . The source tab in my code editor displays extra syllables like ,....<< etc which i'm unable to delete. But the code which is done compiles properly though all these extra syllables are present . Can someone suggest options which i might have enabled/disabled wrongly which led to this issue? Thanks in advance.
I guess you are talking about code folding feature which allows you to fold some parts of the code which are not 'that' interesting at the moment. In the left margin you see a '+' sign which when you click on it shown the 'folded' code.
You can disable this in the menu 'tools->preferences->Code Editor->Display'. Here you uncheck the 'Show Code Folding Margin' and you always see all code.
