錯誤在於 你欲將 0x106 (超果 0x100) 的 RAM Size 硬塞到 BANK4 裡導致錯誤。
可以在便亮宣告前加入 BANKn (n 為指定的BANK) 即可將變量指到想要的 BANK 裡。

上次问过的帖子太弱，希望这个问题能有点技术含量呵呵
错误如下： Error [491] ; . can't find 0x106 words for psect "param4" in segment "BANK4" 我是边加功能边调试的，加功能前的编译结果： Data space: RAM used 0h ( 0) of F54h bytes ( 0.0%) BIGRAM used 0h ( 0) of F54h bytes ( 0.0%) BANK0 used 0h ( 0) of 100h bytes ( 0.0%) BANK1 used 0h ( 0) of 100h bytes ( 0.0%) BANK2 used 0h ( 0) of 100h bytes ( 0.0%) BANK3 used 0h ( 0) of 100h bytes ( 0.0%) BANK4 used FFh ( 255) of 100h bytes ( 99.6%) BANK5 used 0h ( 0) of 100h bytes ( 0.0%) BANK6 used 0h ( 0) of 100h bytes ( 0.0%) BANK7 used 0h ( 0) of 100h bytes ( 0.0%) BANK8 used 0h ( 0) of 100h bytes ( 0.0%) BANK9 used 0h ( 0) of 100h bytes ( 0.0%) BANK10 used 0h ( 0) of 100h bytes ( 0.0%) BANK11 used 0h ( 0) of 100h bytes ( 0.0%) BANK12 used 0h ( 0) of 100h bytes ( 0.0%) BANK13 used 0h ( 0) of 100h bytes ( 0.0%) BANK14 used 0h ( 0) of F4h bytes ( 0.0%) BANK15 used 0h ( 0) of 61h bytes ( 0.0%) COMRAM used 15h ( 21) of 60h bytes ( 21.9%) NVRAM used 0h ( 0) of 60h bytes ( 0.0%) 按USER MANUAL的解释，可能为总RAM空间不足或我的psect过大需程序调整，由上可见实际使用RAM空间很小，可排除前一种可能；BIGRAM空间可以存储大于100h的psect，而我的psect绝不会超过BIGRAM空间，可排除第二种可能。 HI-TECH官网和大陆论坛也找过，除上述两种可能性外，提出加BANK指定的方法，但这仅适用于PICC16之类，PICC-18 PRO对RAM空间自动分配，无需用户指定BANK区，排除。 应该是我哪里理解有问题，LINKER未自动为我分配至BIGRAM，指教！
