Thanks Chandan. Examples in this link
http://www-01.ibm.com/support/knowledge ... ubstr.dita has helped me. Giving it here for reference:
Example 1: FIRSTNME is a VARCHAR(12) column in sample table DSN8A10.EMP. When FIRSTNME has the value 'MAUDE':
SUBSTR(FIRSTNME,2,3) -- 'AUD'
SUBSTR(FIRSTNME,2) -- 'AUDE'
SUBSTR(FIRSTNME,2,6) -- 'AUDE' followed by two blanks
SUBSTR(FIRSTNME,6) -- a zero-length string
SUBSTR(FIRSTNME,6,4) -- four blanks
