Move operations transfer all or part of factor 2 to the result field. Factor 2 remains unchanged. Factor 1 must be blank. Resulting indicators can be specified in positions 54 through 59., except for the MOVE and MOVEL operations if the result field is an array, or for the MOVEA operation if the result field is an array or array element.

In the move operations, factor 2 and the result field are generally of the same type (both numeric or both character). However, you can use the move operations to change numeric fields to character fields and character fields to numeric fields. To change a numeric field to a character field, enter the name of the numeric field in factor 2 and specify a character result field. To change a character field to a
numeric field, enter the name of the character field in factor 2 and specify a numeric result field.
