Library /sys$common/syshlp/dbg$help.hlb DEBUG, Language Support, Fortran, Initialization Code  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    When you debug a program that compiled with the /CHECK=UNDERFLOW
    or /PARALLEL qualifier, a message appears, as in the following
    example:

    DBG> RUN FORMS
    Language: FORTRAN, Module: FORMS
    Type GO to reach main program
    DBG>

    The "Type GO to reach MAIN program" message indicates that
    execution is supended before the start of the main program, so
    that you can execute initialization code under debugger control.
    Entering the GO command places you at the start of the main
    program. At that point, enter the GO command again to start
    program execution, as with other types of Fortran programs.
