You can use the __near or __far keywords with the __based keyword when declaring a function. In programs that use overlays, you can reduce swapping by using __based to group together functions that frequently call one another. You also can use __based to ensure that near functions reside in the same segment as the functions that call them. For example: // FILE 1 - compiled under large model void __based(__segname("MYSEG")) farfunc() // far by default { nearfunc(); } // FILE 2 - compiled under large model void __near __based(__segname("MYSEG") nearfunc() { // ... } If these two functions were not declared as based, this program would suffer a runtime error. Since both functions are based in the MYSEG segment, the program executes correctly. -♦-
