Browsing global variables

In the Symbol Browser, from the Symbols drop-down, choose COMMON variable.
Select the Signatures check box.
All common variables defined in the project, their types and in which files they are defined are now displayed in the Symbol List.
Notice that there are two entries in the Symbol List that begin with

cv DOUBLE PRECISION(:,:) DFV:AV
Both entries refer to the double precision variable AV , which is defined in common block DFV . In the first entry, the common block is defined in the file comdopr.inc . In the second entry, it is defined in the file evclid1.f .
Select the entry in which the common block is defined in evclid1.f .
Choose Info > DFV:AV Referred-By.
The Cross Referencer appears. In the Graph view, you should see the subroutines and functions that refer to the common variable AV .

- Let's jump to positions in the subroutine
IGECOM where AV is referred to. Select IGECOM in the Graph view and press <SHIFT>- double click.
The Source Editor appears and the file evclid1.f is loaded into it. The cursor is positioned to the first position in IGECOM where AV is referred to (in line 582).
Let's jump to the other references to AV in the subroutine. Choose Show > Next Match. The cursor should now be in line 623.
Choose the command a second time. The cursor is now in line 774.
Choose the command a third time. The cursor is now in line 1058. Notice that we're no longer in subroutine IGECOM , but in ROTSEA .
Close the Source Editor and Cross Referencer.
