No symbol "var" in current context

[Toby White]

I understand that there is no symbol "var" in current context. However:
is there a way to ask gdb "well, which symbols are in current context, 
then?"

Background - I'm using gdb with various Fortran compilers which have
useless debuggers (in this case, NAG, whose own debugger won't even read 
corefiles) and these compilers use weird and wonderful name-mangling 
systems. I suspect in several cases I'm getting the above error messages 
not because the variable has been optimized away, but just because I'm
not clever enough to work out exactly how it's been name-mangled.
