So a computer reading an instruction "IF..THEN" can use it just because somehow "IF..THEN" has some immaterial properties?
The material constitution of words is minor, though necessary for non-verbal communication; the most useful thing about words is their immaterial quality.
Why is that a property of the word? We can communicate without using words. We would attribute meaning to a footprint in the right circumstances!
I guess we don't need minds if words somehow have meaning in them!
Of course, even speech requires the material: mouth, tongue, voice, air-vibrations, an ear drum; but the material, mechanical operations of speech and hearing are one thing. What words mean is the important thing. Meaning is not material.
But why would a meaning be a property of a word rather than something we attribute to a word, or better something we merely try to convey by using a word?

I figured property was not the appropriate word...
Anyway, to explain myself: If I say a word 'has' meaning, that isn't to say that that meaning is somehow intrinsic in the word, or that the word literally contains a meaning the way a pea-pod contains a pea. What I mean is that we understand the meaning of a word, based on what we've been taught about what meaning others have traditionally ascribed to it.
Hence, the word 'brown' 'has' meaning, not in itself as in something constituent to its existence in physical form, but only insofar as the letters b-r-o-w-n, in that order, conveys one or more ideas to the mind of an English language reader. It conveys the idea of a dark color, and/or a surname, depending on the context in which it's used (it can convey other meanings as well, of course, depending on context and on the mind reading it).
Lest I not be clear: when I say a word 'conveys' meaning to the mind, it isn't the word that does the conveying. It's the mind that does the work, drawing meaning from the word.
In the sentence, "The members of Van Halen had all the brown M&Ms removed from the complimentary bowl of M&Ms in their dressing room, because they're arrogant rock stars," the word brown conveys a dark color. In the sentence, "Mr. Brown has eaten the pyjamas and we are now taking him to the emergency room," the word Brown conveys a surname, and a color only by association and habit. We could get into capital letters and what they signify, but why bother?
Your comment about the footprint kind of makes my argument for me:
True, a footprint can have meaning, but, like the physical form of a word, does not have meaning as an intrinsic element or property. A footprint only 'has' meaning insofar as it conveys an idea to a mind: "Hmm, someone wearing size thirteen Reeboks has trod on the floor I just mopped! That clown-footed bastard!"
Short version: meaning is not material.
The problem with these kinds of discussions over words is that they frequently veer into sophistry and tedious navigations of the inny or outy
