RE: Determine if variable exists on make side from sh side

[PATTON, BILLY \(SBCSI\)]

Here's where I'm at now:
REFRESH+ldb+celltools+pub := dogs


all :
        @list=REFRESH+ldb+celltools+pub ;\
        echo "list = '$$list'" ;\
        echo "contents = '$($$list)'" ; \
        def=$(origin $$list); \
        echo "def = $$def" ; \
        if ! [ "$$def" = "undefined" ] ; then \
                echo "if defined"; \
        else \
                echo "else undefined" ; \
        fi
