Moving Through the Source Code

As mentioned above, you can move through a source file displayed in the source window by using the scroll bar on the right side of the window. You can also use the up and down arrow keys to scroll a line at a time, or press the Control key along with the arrow key to move half a page at a time. To return to the current execution point, type Control-x in the source window.

To search for a text string in the current source file, issue the /string or ?string command in the command window. The /string command searches forward in the file for the string that you specify and repositions the file at the first occurrence it finds. The ?string command searches backward in the file for the string that you specify.

You can display different files by choosing the File or Func selection from the File menu; see " Choosing the Current File and Function". You can also move between files. Prism keeps a list of the files you have displayed. With the mouse pointer in the source window, do this to move through the list:

• To display the previous file in the list, click the middle mouse button while pressing the left button. You are returned to the location at which you left the file.

• To display the next file in the list, click the right mouse button while pressing the left button.
