[mod.computers.vax] How to tell if a global symbols is defined?

hoge@hqafsc-vax.UUCP.UUCP (02/23/87)

There's a lexical function which does exactly what you're looking for (I
think). It's F$TYPE(symbol) and returns one of three values

	INTEGER if the symbol is an integer
	STRING if it's a string or
	a null string if its _undefined_

Hope this helps....
