我用数组变量做循环变量,结果说无法编译!

Prog51331.pas(58,14) Error: Illegal assignment to for-loop variable "B1"

Prog51331.pas(70,22) Error: Illegal assignment to for-loop variable "B2"

Prog51331.pas(72,25) Error: Illegal assignment to for-loop variable "O"

Prog51331.pas(84,27) Error: Illegal assignment to for-loop variable "O"

Prog51331.pas(103) Fatal: There were 4 errors compiling module, stopping

Fatal: Compilation aborted

白交了两次,然后再自己重新编了一个另外的程序,郁闷!

是不是应该换个版本高一些的fp啊?
