如何为用于多个数据集的所有属性创建宏变量

Question

我有一个长长的属性列表，用于我的 SAS 代码中的多个数据集，但我不知道如何创建一个宏变量，该变量将允许我避免重新输入这个长长的属性列表，只有宏变量允许我做一些事情，比如重复 sysUser 或日期。我的属性列表在下面的代码中：

attrib
    Subj        label = "Subject Number"                        
    sfReas      label = "Screen Failure Reason"                 length = $ 50
    sfStatus    label = "Screen Failure Status (0 = Failed)"    length = $ 1
    BioSex      label = "Biological Sex"                        length = $ 1
    VisitDate   label = "Visit Date"                            length = $ 10
    failDate    label = "Failure Notification Date"             length = $ 10
    sbp         label = "Systolic Blood Pressure"
    dbp         label = "Diastolic Blood Pressure"
    bpUnits     label = "Units (BP)"                            length = $ 5
    pulse       label = "Pulse"                                 
    pulseUnits  label = "Units (Pulse)"                         length = $ 9
    position    label = "Position"                              length = $ 9
    temp        label = "Temperature"                           format = 5.1
    tempUnits   label = "Units (Temp)"                          length = $ 1
    weight      label = "Weight"  
    weightUnits label = "Units (Weight)"                         length = $ 2
    pain        label = "Pain Score";

谁能告诉我如何创建一个宏变量来编码所有这些？

Answer 1

因为您似乎想将单个语句的一部分存储到宏变量中，这应该很容易。

%let common=
Subj        label = "Subject Number"                        
sfReas      label = "Screen Failure Reason"                 length = $ 50
sfStatus    label = "Screen Failure Status (0 = Failed)"    length = $ 1
BioSex      label = "Biological Sex"                        length = $ 1
VisitDate   label = "Visit Date"                            length = $ 10
failDate    label = "Failure Notification Date"             length = $ 10
sbp         label = "Systolic Blood Pressure"
dbp         label = "Diastolic Blood Pressure"
bpUnits     label = "Units (BP)"                            length = $ 5
pulse       label = "Pulse"                                 
pulseUnits  label = "Units (Pulse)"                         length = $ 9
position    label = "Position"                              length = $ 9
temp        label = "Temperature"                           format = 5.1
tempUnits   label = "Units (Temp)"                          length = $ 1
weight      label = "Weight"  
weightUnits label = "Units (Weight)"                         length = $ 2
pain        label = "Pain Score"
;

然后，您可以在创建 ATTRIB 语句时使用该宏变量。

data want;
  attrib &common
    Xvar1 length=8 label='Extra Variable 1'
    Xvar2 length=$20 label='Extra Variable 2'
  ;
  set have;
run;
