要在NCL中直接赋值定义一个字符变量并不是件容易的事情,你必须使用字符 对应的ASCII值并才上C后缀来实现。一个更人性化的方法是使用函数tochar或者在6.0.0版本以下,你可能需要使用stringtocharacter。比如创建一个c字符你可以a = 99C或者a = tochar("c")。

How do I create a double, long, short, or byte variable without using new or one of the conversion routines, like integertobyte? How do I include the double quote () character in an NCL string? Can NCL prompt for user input? Is it possible to have global variables in NCL? How can...
