The CAT, CATT, CATS, and CATX functions in SAS all concatenate character strings but have additional features. CAT concatenates strings, CATT removes trailing blanks, CATS removes trailing and leading blanks, and CATX removes blanks and inserts separators between strings. The functions can be used to combine variable values or other character data into one string.

2. Functions: CAT / CATT / CATS / CATX
• These functions operate around 4 actions
1. Concatenates character strings
2. Removes trailing blanks
3. Removes leading blanks
4. Inserts separators

3. Functions: CAT / CATT / CATS / CATX
• CAT():
1. Concatenates character strings
Syntax: cat(var1,var2,….)
Equivalent code: var1 || var2 ||….

4. Functions: CAT / CATT / CATS / CATX
• CATT():
1. Concatenates character strings
2. removes trailing blanks
Syntax: catt(var1,var2,…)
Equivalent code:
Trim(var1)||Trim(var2)||…..

5. Functions: CAT / CATT / CATS / CATX
• CATS()
1. Concatenates character strings
2. removes trailing blanks
3. removes leading blanks
Syntax: Cats(var1,var2,….)
Euivalent code:
TRIM(LEFT(X1))||TRIM(LEFT(X2))||…..

6. Functions: CAT / CATT / CATS / CATX
• CATX():
1. Concatenates character strings
2. removes trailing blanks
3. removes leading blanks
4. inserts separators
Syntax: Catx(SP,var1,var2,…)
E.C: TRIM(LEFT(X1))||SP||TRIM(LEFT(X2))||SP||…..
Note:SP=Separator
