        cpu     sc/mp

        ; by default, SC/MP uses C notation, i.e. the following
        ; is interpreted as octal:

        ldi             044     ; 44 octal -> 36 decinal

        ; now disable the C-like octal syntax, which means parsing
        ; falls back to default decimal:

        intsyntax       -0oct
        ldi             044     ; 44 decimal

        ; now, enable the National-specific hex syntax with leading zero:

        intsyntax       +0hex
        ldi             044     ; 44 hex -> 68 decimal

        ; C-octal and National-hex cannot be enabled at once:

        expect  2231
        intsyntax       +0oct
