John McKown's description of how the assembler handles alphabetic case characterizes its default behavior correctly.
Finer control is, however, available. Specifying either or both of the keyword values NOCASE and NOMACROCASE of the COMPAT assembler option instructs the assembler NOT to make the replacements of minuscules with majuscules that it would oitherwise make, in the corresponding places.
