#define ASSIGN_VAR	(	MAP,
		VAR
	)

Value:

{ \
    const auto it = MAP.find(#VAR); \
    if(it!=MAP.end()) { \
        VAR = it->second; \
    } \
    else \
        SETERRQ2(PETSC_COMM_SELF,1,"Key %s not found in %s",#VAR,#MAP); \
}

Assign a value into key-variable and throw a proper PETSc error when lookup fails.
