Utility Macros

These are macros that may be used within higher level macros.

• words.sas (rev=1): Counts the words in a string (used only for byvars where shortcut lists not allowed). This is taken directly from p256 of the SAS Macro manual.
• Varlist.sas (rev=1): takes a shortcut list of SAS variables as input and returns the expanded list of variable names.
• CheckVar.sas (rev=1): Checks that needed variables exist in a particular data set.
• quartiles.sas (rev=3): Creates quartile versions of continuous variables. Updated 3/26/08.
• Univariate.sas (rev=3): Calculates summary statistics for specified variables. Updated 3/26/08.
• RefDummy.sas (rev=1): Finds the reference values for categorical variables and creates dummy variables. Updated 4/22/08.
• dummy.sas (rev=1): Creates dummy variables for categorical variables. Updated 4/22/08.
• residsqr.sas (rev=1): Calculate the average studentized residuals within each 10-percentile. Updated 4/22/08.
• TransposeMany.sas (rev=1): Contains a long2wide and wide2long macro for transposing many variables at once

• NextWord.sas: (rev=1): Macro function that returns the first word from a list. (More NextWord.doc)

• CheckData.sas: (rev=1): Function that checks the existence of a dataset. (More CheckData.doc)

• CheckVariab.sas: (rev=1): Function that checks the existence of a variable. (More CheckVariab.doc)
