大家在InstallShield中用InstallScript脚本编程时，有没有意识到其实它是有限制的？
下面是编译脚本文件的限制（setup.inx）：
- Maximum number of statements: about 4,294,967,295 （如果超过此限制，在安装初始化时会报错误 -5009）
- Maximum number of global variables: about 196,605 （65,535 numbers, 65,535 variants, 65,535 strings）
- Maximum number of typedefs: about 65,535
- Maximum number of prototypes: about 65,535
- Maximum number of functions: about 65,535
- Maximum number of statements per function: about 65,535
- Maximum local variables per function: about 196,605 （65,535 numbers, 65,535 variants, 65,535 strings）
下面是脚本文件的限制（.rul）:
- Maximum line 1,024 characters
- Maximum number of nested include files: 80
- Maximum number of include files: 2,048
- Maximum identifier length: 63 characters
- Maximum number of macro expansions: 100
- Maximum macro expansion text length: 256 characters
- Maximum file name length: 256 characters
- Maximum number of nested #if statements: 10
- Maximum number of parameters per function: 16
如果上述有一个或多个限制被超越，则会出现编译错误。
InstallShield建议，如果遇到上述超限的问题，可以考虑减少代码降低安装脚本的大小，或者将安装脚本分散到多个工程中，然后通过主安装包调用各个子安装包。
