Microsoft Makro Derleyicisi BNF Dil Bilgisi
Bu sayfa, MASM dil bilgisinin BNF açıklamasını içerir. Başvuruya ek olarak sağlanır ve tamamlanması garanti değildir. Anahtar sözcükler, parametreler, işlemler vb. hakkında tam bilgi için başvuruya başvurun.
BNF'nin kullanımını göstermek için, aşağıdaki diyagramda yönergenin TYPEDEF tanımı, ile başlayan ve sonlandırıcı typedefDirolmayan ile birlikte gösterilmektedir.
Her yatay ayraç altındaki girdiler , NEAR32, FAR16ve FAR32gibi NEAR16terminallerdir. Veya , , , distanceve protoSpec gibi qualifierqualifiedTypedaha fazla tanımlanabilir terimler değildir. Tanımdaki typedefDir her italik olmayan, BNF'deki bir girdidir. Üç dikey nokta, basitlik açısından bu şeklin göstermediği, noktalı olmayan bir dallanma tanımını gösterir.
BNF dil bilgisi özyinelemeli tanımlara izin verir. Örneğin, dil bilgisi için olası bir tanım qualifiedTypeolarak kullanır qualifiedType ve bu da için qualifiertanımın bir bileşenidir. "|" simgesi, alternatif ifadeler arasında bir seçim belirtir, örneğin endOfLine | comment. Çift ayraçlar isteğe bağlı bir parametre belirtir, örneğin ⟦ macroParmList ⟧. Köşeli ayraçlar aslında kaynak kodda görünmez.
