All leading blanks on the second operand are not truncated. For example: ABC *TCAT DEF becomes ABCDEF ‘ABC ‘ *TCAT DEF becomes ‘ABCDEF’ ABC *TCAT ‘ DEF’ becomes ‘ABC DEF’ ‘ABC ‘*TCAT ‘ DEF’ becomes ‘ABC DEF’ -All blanks that surround the concatenation operator are ignored, but at least one blank must be on each side of the reserved value operator (*CAT, *BCAT, or *TCAT).
