C Spec is mandatory because we need to specify SETON LR in

a compilation error.

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

Answer / t thomas
%check validates a string character by character to a
particular set of characters and gives 0 if that character
in the string is not present in our set else give the
position.
%scan checks in a string whethere a string or character is
present in another string and also gives the start position.
