The include modules are composed of structure, record, and common statement= s. These include modules are used to standardize the common block variable nam= es throughout the program. The common statements only occur in the include= modules. This program was first built in 1984 and very significantly modified in 199= 7. Currently we are compiling with Gfortran. We now need to modify this program and to use the gdb interactive debugger.= However gdb debugger does not seem to give visibility of variables define= d in the structures and records.? Can you make a suggestion or point me to a person who knows about this issu= e? Will the new gdb debugger version 9.1 help? Thanks. Paul Cefola -- Dr. Paul J.
