For the assignment gv_target = gv_source, which data declarations will always work without truncation or rounding?

The reasoning for selecting the pathway where a data declaration involving a character type variable transferring to a string variable will always succeed without issues such as truncation or rounding lies in the fundamental nature and characteristics of the data types involved.

When you declare gv_source as a character type (c), it can store a fixed-length sequence of characters, while gv_target is a string, which is a variable-length data type. This flexibility allows a string to hold any content from the character type without losing data, as strings can dynamically resize to accommodate the full length of the source data.

In contrast, when transferring data from a packed number to a shorter packed number, or from a date type into a string, there is a risk of encountering truncation or conversion issues. Specifically, packed decimal types have fixed lengths and can be sensitive to changes in size and decimal places, potentially leading to data loss or rounding effects. Similarly, transferring a date type into a string could require a specific format, potentially resulting in mismatched representation or loss of information if not handled carefully.

This ensures that B is accurate because the inherent characteristics of the string data type allow for a seamless transfer from a fixed character type without constraints, avoiding any issues relating to data loss
