Performing function body cross referencing

In the Source Editor, make sure that subroutine

DGECOM is selected in either the Symbol List or in the Text View. Then, choose Info > DGECOM Refers-To.
A Cross Referencer appears. Subroutine DGECOM is shown in with all the symbols it refers to (77 nodes). For a description of the abbreviations used in the Cross Referencer, please refer to Abbreviations used in the Cross Referencer.

- Let's see which subroutines and functions are called by those which
DGECOM calls. To do so, first enter 3 in the Depth field. Then, press the Filters... button.
The Filter dialog appears.

- Limit the scope of the next query to subroutines and functions by pressing the None button under Types and then clicking on the subprogram (s) check box.
- Now, with s DGECOM selected in the Cross Referencer's Graph view, press the Refers To button in the Filter dialog.
  You should now see a call tree similar to the following:

- Reset the Depth field to 1 and press Return.
- Close the Cross Referencer and Source Editor tools.
