Difference Between Scan and Check Operators
'D' SCAN 'Hardcore' Res
'D' Check 'Hardcore' Res1
'D' Check 'Dragon' Res2
Res = 4 , Res1 = 1 , Res2 = 2
Scan always gives the position where the search string is
found.
Check always gives the position of First non-existent
Position. Hope the RES1 and RES2 example will give you an
idea of CHECK opcode
