\DOC ascii_EQ_CONV
\TYPE {ascii_EQ_CONV : conv}
\SYNOPSIS
Decision-procedure for equality of ascii character constants.
\DESCRIBE
The conversion {ascii_EQ_CONV} implements a decision procedure for the equality
of ascii character constants built up from boolean constants {T} and {F} using
the constructor {ASCII}. The conversion expects its term argument to be an
equation of the form:
{
"ASCII a1 a2 a3 a4 a5 a6 a7 a8 = ASCII b1 b2 b3 b4 b5 b6 b7 b8"
}
\noindent where each of {a1}, ..., {a8}, {b1}, ..., {b8} is either the constant
{T} or the constant {F}. Given such a term, the conversion returns:
{
|- (ASCII a1 a2 a3 a4 a5 a6 a7 a8 = ASCII b1 b2 b3 b4 b5 b6 b7 b8) = T
}
\noindent if {ai} is identical to {bi} for i from 1 to 8. Otherwise,
the conversion returns:
{
|- (ASCII a1 a2 a3 a4 a5 a6 a7 a8 = ASCII b1 b2 b3 b4 b5 b6 b7 b8) = F
}
\FAILURE
Fails if applied to a term that is not of the form shown above.
