| 10A7 | Receiver length | Source string | Trim character |
Operand 2: Character scalar.
Operand 3: Character(1) scalar.
Description: The operation determines the resultant length of operand 2 after the character specified by operand 3 has been trimmed from the end of operand 2. The resulting length is stored in operand 1. Operand 2 is trimmed from the end as follows: if the rightmost (last) character of operand 2 is equal to the character specified by operand 3, the length of the trimmed operand 2 string is reduced by 1. This operation continues until the rightmost character is no longer equal to operand 3 or the trimmed length is zero. If operand 3 is longer than one character, only the first (leftmost) character is used as the trim character.
Operands 2 and 3 are not changed by this instruction.
