&sysindex : Contains the number of macros that have started execution in the current SAS job or session. You can use SYSINDEX in a program that uses macros when you need a unique number that changes after each macro invocation. 当宏调用时,会自动产生这个变量,&sysindex的值在调用不同宏时都...
These statements probably look familiar because there are parallel statements in standard SAS code, but don’t confuse these with their standard counterparts.These statements can only be used inside a macro, and can perform actions that would be completely impossible for standard SAS statements.With ...
深入解析SAS:宏编程(条件语句、循环语句) 一、宏概述 个人理解macro这个是面向过程的SAS语言面向对象编程的一小步。有一点点类似于R语言中的function函数,或者python中的自定义class,为了提高编程效率,macro是不得不学习的内容。 宏和宏变量 SAS宏代码包括两个基本部分:宏命令和宏变量。宏变量通常加一个“&”作为前...
SAS宏变量作用范围只有有两种,一种是全局的(global),另一种是局部的(local)。全局的宏变量一旦声明或者定义之后,可以在当前SAS Session的任何地方,不管是open code还是macro当中访问,而局部变量则只能在特定的范围内访问。 1) 任何在open code当中定义的宏变量一律都是全局的,不管定义的方式是通过%let语句,还是通过...

The macro and ODS components of this method are simple and straightforward from a SAS code standpoint. They should not deter beginning level programmers from adopting this method. The real 'meat' of this programming mostly exists in the data step programming, which will be used to format a ...
Introduction The Macro Language serves as an extension to the SAS System for the purpose of generating text in the form of SAS code, including partial and/or complete statements, DATA steps, PROC steps, variables, text strings, functions, informats, formats, expressions, comparison and logical ...
Increase the modularity, flexibility, and maintainability of your SAS code with the SAS macro facility. This comprehensive reference provides complete information about macro language elements, interfaces between the macro facility and other parts of SAS software, and macro processing in general. With th...
在说程序前,还是要说一个东西,DVP(Data Validation Plan,数据验证计划)是由数据部门的DM编写,里面的是对临床试验收集的数据点进行验证的规则及其描述,SAS Programmer/Database Designer会更具DVP来实现一条一条的Edit Check,Edit Check 又分Online 和offline俩种,由于今年EDC系统的更新换代,很多核查都以及Online了,对...
