PowerBasic的常用函数
PowerBasic是BASIC语言的一种编译器,编译出来的EXE或者DLL结构非常紧凑,执行速度跟C不相上下。编译出来的DLL也是标准DLL,不需要像VB那样拖着一个笨重的库文件。通常PowerBASIC 编译的代码在性能上比VB 编译的代码好3到23 倍, 产生的可执行文件比VB生成的可执行文件小4 到40 倍。我的很多很多工程里用的DLL都是由这个编译的。至于语法,和VB基本一致,所以上手很容易。最爽的是powerbasic里面有指针,变量指针还是函数指针都可以只用,所以能很容易的从C的代码翻译成powerbasic可编译的代码。
这里我贴出来一下powerbasic里面常用的函数,方便大家写代码(我下的时候就是一个本文,我也没有整理,直接贴出来吧,大家用哪个函数就复制哪个Function吧。。。):
