Question

VB中的 dim是什么意思了`` 急`

Answer 1

下面是一个外国网友的回答：

Dim originally (in BASIC) stood for Dimension, as it was used to define the dimensions of an array.
(The original implementation of BASIC was Dartmouth BASIC, which descended from FORTRAN, where DIMENSION is spelled out.)
Nowadays, Dim is used to define any variable, not just arrays, so its meaning is not intuitive anymore.

意思是dim在BASIC里面原来指的是dimension, dim被用来定义一个数组的维度。
BASIC来自于达特茅斯BASIC，后者来自于FORTRAN, FORTRAN里面DIMENSION就是DIM.
现在Dim被用于定义任何变量，而不仅仅是数组了。它就这样被发扬光大了。
