出現以上錯誤的原因主要是第一個(gè)原因，第一個(gè)原因導致了它下面所有錯誤，第一個(gè)原因是：

ERROR L107: ADDRESS SPACE OVERFLOW

SPACE: DATA

SEGMENT: ?DT?GMNS_3V4

LENGTH: 0014H

說(shuō)明data空間已經(jīng)不夠用，原因是你可能有好多函數，而函數內部的局部變量又沒(méi)有定義其空間，這種情況下，系統會(huì )將變量分配到你在Otions for Target 對話(huà)框里的設置的空間。如果你在下圖所示中的 Memory Model 里設置成 Small:variables in DATA,則DATA空間很快便用完，導致data空間不夠用。解決的辦法有兩種，一是通過(guò)更改Memory Model設置，可以設置成pdata或xdata，以便有足夠大的空間，但這又帶來(lái)新的問(wèn)題，程序運行速度減慢，而且code代碼也會(huì )加大，因為如果一個(gè)局部變量被存放在了xdata空間，匯編語(yǔ)言訪(fǎng)問(wèn)xdata空間的代碼大小要比訪(fǎng)問(wèn)data空間的代碼大，變量一旦很多，程序的代碼也會(huì )逐漸增大；二是根據自己的要求設置變量的空間。所以這涉及到代碼優(yōu)化的問(wèn)題，遇到具體問(wèn)題時(shí)，在運行速度和代碼大小之間取得適合自己的情況。
