When you have a map open in the BMS Painter, you can:
Fields can be single or repeating and you define them by specifying text or by marking the relevant area on the map in the painter window.
Any string of characters that you specify on a map is automatically generated by the painter as an autoskip BMS field. You must explicitly define any field you intend to use for displaying or accepting variable data; see the section Defining Field Properties.
You can define groups of fields, for which you can specify common attributes for all the fields in the group. When you define a standard BMS group, you generate both a value for the BMS GRPNAME operand and a group item in the copybook.
You can define an SDF array by creating additional occurrences of a single field that you have already defined. The field must have a name defined for it on the Field Properties dialog box either in Field Name on the General page or in Name in the Field section on the SDF page. In the latter case the painter generates a field name on the General page.
To create an SDF group or an SDF array you must have enabled the SDF option in the BMS file properties. See Build Settings for the BMS Painter.
You can move fields within a map either as single fields or in groups of fields. You can move fields between maps using the clipboard
You can copy fields within a map either as single fields or in groups of fields. When a field is copied, its properties are copied as well, except for any SDF array or SDF group information.
You can delete fields and groups of fields.
