Answer: A, C, E

Explanation:

The patterns that raise an exception are those that use the constructor operator EXACT to perform a lossless assignment or calculation, but the result cannot be converted to the target data type without data loss.

The following are the explanations for each pattern:

A: This pattern raises the exception CX_SY_CONVERSION_LOST because the result of the calculation 2 * 3 is 6, which cannot be assigned to a packed number with two decimal places without losing the integer part. The operator -U is used to perform a lossless calculation with the calculation type decfloat34.

B: This pattern does not raise an exception because the result of the substring expression

gco_string+5(5) is ‘6789A’, which can be assigned to a string without data loss. The operator EXACT # is used to perform a lossless assignment with the data type of the argument.

C: This pattern raises the exception CX_SY_CONVERSION_LOST because the result of the substring expression gco_string+5(6) is ‘6789AB’, which cannot be assigned to a character field with length 5 without losing the last character. The operator EXACT is used to perform a lossless assignment with the data type of the target field.

D: This pattern does not raise an exception because the result of the calculation 2 / 2 is 1, which can be assigned to a packed number with three decimal places without data loss. The operator -U is used to perform a lossless calculation with the calculation type decfloat34.

E: This pattern raises the exception CX_SY_CONVERSION_ERROR because the constant gco_date contains an invalid value ‘20331233’ for a date data type, which cannot be converted to a valid date. The operator EXACT is used to perform a lossless assignment with the data type of the target field.
