I should probably just drop it because I reveal my ignorance when I post, and erik is the only one who has shown any interest, but ...
I guess what I want is for eqn to sort of immediately convert GAMMA to Γ and then go about its business with Γ, as if it never saw the word GAMMA, got it? So, I was looking at eqn -d to get some more feedback and it seems that a user definition does that. Here's some output. cpu% eqn -d ... eqn version Oct 24, 1991 .lf 1 - .EQ .EQ define Gamma %Γ% . lex token = |define| . name Gamma defined as Γ Gamma . lex token = |Gamma| . found Gamma|=Γ| . lex token = |Γ| . 57346text: S11 <- \f2Γ\fP; b=0,h=1,lf=2,rf=2,ps=10 .ds 11 "\f2Γ\fP cpu% eqn -d ... eqn version Oct 24, 1991 .lf 1 - .EQ .EQ Γ . lex token = |Γ| . 57346text: S11 <- \f2Γ\fP; b=0,h=1,lf=2,rf=2,ps=10 .ds 11 "\f2Γ\fP Of course, I don't know if the treatment is the same in other contexts, but I'm wondering if a simple solution is to make gktbl and treat it like deftbl in lex.c instead of like restbl in text.c.
