C !ROUTINE: GETCON
C !INTERFACE:
FUNCTION GETCON(NAME)
C !DESCRIPTION:
C Generic function getcon is a repository of global variables,
C i.e. a memory for scalar values needed throughout a large
C program. This function remembers floating point values. The
C function is called with a character name to interrogate a value.
C !USES:
implicit none
