9.1.2 Calling Tree (C)

The calling tree is listed after all program units have been compiled. Each program unit's calling tree consists of the SUBROUTINEs and FUNCTIONs called in that program unit. A listing of variables and arrays used (both from the original source program and in code which KAP added) precedes the calling information.

After the cross-reference and calling tree information for the last program unit in the file, the calling tree information for the entire source file is summarized, for example:

      CROSS REFERENCE TABLE
