Sample 37433: Rename each variable in a data set by adding a prefix The sample code that is illustrated on the Full Code tab uses the %SYSFUNC function along with certain SAS ® functions to retrieve the variable names. 2018-05-29 · Use the colon operator to specify a prefix If you want to use variables that have a common prefix but have a variety of suffixes, you can use the colon operator (:), which is a wildcard character that matches any name that begins with a specified prefix. 2011-11-28 · The KEEP= statement drops any variables that you don't want; the _ALL_ keyword reads in all variables that remain. Consequently, the matrix m contains all variables that begin with the prefix "x" (assuming they are all numeric or all character). Tags Getting Started Reading and Writing Data Tips and Techniques.
The fetch action displays the table Cholout. The NAME= option allows you to change the name of the _NAME_ variable. It is the name of the variable that is transposed. 2. The PREFIX= option allows you to change the prefix " COL ". In a previous section we discussed the PREFIX options. With this option you can change the prefix of the new column names.
When you do character comparisons, you can use the colon (:) modifier to compare only a specified prefix of a character string. For example, in the following WHERE expression, the colon modifier, used after the equals sign, tells SAS to look at only the first character in the values for variable LASTNAME and to select the observations with names beginning with the letter S:
Loading. RESOURCES z6. tells SAS to add 'k' number of leading zeros to the variable 'x' to maintain 6 as a length of the newly transformed variable 'xx'.In this case, 'k' = (6 - number of values in each observation in variable 'x').

The word NOT and its equivalent symbols are also prefix operators. Hi all, Need some help in rename the variables. I am going to add prefix ahead of each variable,eg (listed below the sample dataset): rename C2 to SC2; C10_1 to SC10_1; I have 618 variables in my dataset,all of them need to add the same prefix ahead the original variable name. PREFIX= prefix specifies a prefix to use in constructing names for transposed variables in the output data set. For example, if PREFIX=VAR, then the names of the variables are VAR1, VAR2, …,VAR n. Member names are typically capitalized internally in SAS, even if they're not capitalized in your code.

To rename the COL# variables, we use the prefix option to specify a prefix to the sequentially numbered variables. In the SAS code below, the COL# variables can be renamed to be Amount1, Amount2, Amount3 etc., by specifying prefix=Amount. When you do character comparisons, you can use the colon (:) modifier to compare only a specified prefix of a character string. For example, in the following WHERE expression, the colon modifier, used after the equals sign, tells SAS to look at only the first character in the values for variable LASTNAME and to select the observations with names beginning with the letter S: SAS ramp up continues with US west coast as next step.
