Dot is the namespace separator, so it is not a definition of instruction called "B.EQ", but a definition of instruction called "EQ" in the "B" namespace. For "B" namespace to be case-insensitive, it needs such symbol to be defined to anchor it:
define B? ; prepare namespace
calminstruction B.EQ? operands&
end calminstruction
Note that you also need to avoid having a case-sensitive symbol with the same name, as it would then take precedence:
B? = 1
B = 2
macro b.EQ? ; same as: macro B?.EQ?
display 'I'
end macro
macro B.EQ? ; this selects the second namespace, because case-sensitive takes precedence
display 'S'
end macro
B.EQ ; S
b.eq ; I
B?.EQ ; I I do not recommend ever having both case-insensitive and case-sensitive variants of the same symbol, but it is worth keeping in mind how it behaves then.
