The following are some of the types of the DFHMDF present in the CICS set:

  • POS: POS stands for the position in the CICS. The POS parameter helps to indicate the row and column position in the field that is relative to the upper left corner of the map position.
  • Length: The length always indicates the characters that are present in the field. In the length, the attribute bytes are not present so each of the lengths will occupy one more column as compared to its length value.
  • ATTRB: ATTRB stands for the field attribute. Usually, the field attribute is not required in the BMS. This is because the BMS always uses the default value of the auto-skip protection, normal intensity and the modified tag on.
  • Initial: Initial is also not needed in the BMS. You can only use the initial in the label and the title field that already has a constant value in the BMS.
  • Picout: Picout is one of the definitions of the filed CHG. It helps to tell the BMS that what types of pictures is mainly used to generate the fields. The Picout will also help you edit the facilities of the COBOL or the PL/I as you move the data into the map.
  • GRPNAME and OCCURS: GRPNAME and OCCURS options always do not appear in the simple example, because they are one of the most complex forms. The GRPNAME are always used to subdivide a map field within the program for the later processing and the OCCURS will mainly help you to define adjacent.
