A local variable is one that can only be referenced within the block in which it is declared and a global variable is available throughout a program. 一种被指定属性的存储单元，用于存放特定的数据或参数，它们在程序执行时可改变。变量 可以是字、字符串、数组或栈。二维或多维变量是结构变量。局部变量只可在其被说明的模块 中引用，全局变量可在整个程序中引用。 6.

In FORTRAN, a data item that is not an array or array element, identified by a symbolic name. 在FORTRAN语言中，由符号名标识的非数组或非数组元素的一种数据项。 8. In PL/1, a named entity that is used to refer to data and to which values can be assigned. Its attributes remain constant, but it can refer to different values at different times. Variables fall into three categories, applicable to any data type: element, array, and structure. Variables may be subscripted, qualified, or both, or may be pointerqualified. ㏄L/1语言中一种命名的实体，用来表示数据，且可对其赋值。变量属性保持不变，但在 不同的时间，可表示不同的值。变量分三类：元素、数组和结构，能适用于任何数据类型。变量 可带下标、可被限定或两者兼有，也可用指针限定。 |
