Tips On SaS Functions Well Explained

  !) Function:   COMPBL Purpose:   To replace all occurrences of two or more blanks with a single blank character.  This is particularly useful for standardizing  addresses and names where  multiple blanks may have been entered. Syntax : COMPBL(character-value)                                 character-value is any SAS character value.             If a length has not been previously assigned, the length of the resulting             variable will be the length of the argument Example: Using the Combl function to convert multiple blanks to single blank. ***Primary function: COMPBL; data squeeze; input # 1 @ 1 Name $20. # 2 @ 1 Address $30. # 3 @ 1 City $15.    @ 20 State $2.    @ 25 Zip $5. ;   Name = compbl(Name);   Address = compbl(Address);   City...

!) Function:   UPCASE Purpose:   To  change all letters to uppercase.                                                  NOTE: The corresponding fuction LOWCASE changes uppercase to lowcase Syntax : UPCASE(character-value)                                 character-value is any SAS character value.             If a length has not been previously assigned, the length of the resulting             variable will be the length of the argument Example: ***Primary function: UPCASE ***Other function: DIM; data mixed;   length a b c d e $ 1 ;   input a b c d e x y;   datalines ;   M f P p D 1 2   m f m F M 3 4 ; run ;   data upper;   set mixed;   arra...

 For the situations where you  only have month, day , and year values but do not have a SAS Date, the MDY functon can create a SAS date value, given the value for the month, day , and year .Kindly find a detailed example on how this is made possible in SAS Purpose:   To create a SAS Date from the month, day and year. Sytax: MDY(month, day, year)               month is a numeric variable or constant representing the month of the year (a number               from 1 to 12 ).               day   is a numeric variable or constant representing  the day of the month (a number                  from 1 to 31 ).               year  is a numeric variable or constant representing the year. Values of the month, day and time that do not define a valid date result in a missing value and...

Function That Sorts Character Values       Purpose : To sort the values of its character arguments in ascending order   Syntax : CALL SORTC(<of> Char-1 <, … Char-n>)                        Char-n is a character variable. If you use a variable list in the form                       Var1–Varn, precede the list with the word "of"'.                      Arguments to the CALL SORTC routine cannot be constants. You may use                      array references as arguments to this routine as well (see the following examples):         Examples   ...

 Function: Call Sortn Purpose: To sort the values of its numeric argument in ascending order. Syntax :  CALL SORTN(<of> Vaar-1 <,  ... Var-n>)               Var-n  is a numeric variable. If you use a variable list in the form VAR1-Varn,                               precede   the list with  the word "of".               Arguments to the CALL SORTN routine cannot be constants. You may use   array                    references as   arguments to this routine as well (see the following examples)    Examples For these examples, x1=8, x2=2, x3=., x4=1, a=9, b=7, c=8. Also, an array is defined as array nums[4] x1-x4;        Call Routine                  ...
