7.110.4 SELECT_SQL Free Format Coercions

Following are some examples of the results that may be expected when using SELECT_SQL when the column field type and the LANSA field type are not the same - thus coercion needs to occur.

Test Values were all numeric. If an Alpha/String contains non-numeric data, the coercion to numerics is undefined. It may result in 0, it may ignore non-numeric characters and convert the rest, and it may ABEND.

Note that overflow of a value is undefined. For example, if a number is too large to fit in to a field, it may truncate left or right or indeed be an indeterminate value. On IBM i, it is usually a fatal error.

Where NO is stated, coercion is performed, but valid coercions are not common due to formatting requirements.
