Notes on :
  1. SMCS screen size requires a minimum screen size of 24 rows x 80 columns to display the SMCS Console Selection Screen. SMCS consoles that do not have a predefined LU should be at least 24x80.
  2. 3270–X and SMCS values are calculated dynamically as follows:
    Full Capability AREA Size
    Max
    #rows - #rows of entry area
    Default
    14 or the Max Area, whichever is smaller.
    Status Display AREA Size
    Max
    #rows
    Default
    2 areas, each is #rows/2. (For odd screen sizes, the B area is one row larger so that it takes up the entire screen.)
    Screen Size
    See SMCS Screen Size Note
    SEG Default
    (#rows - (3 or 4))/2, where 3 or 4 depends on the number of lines in the entry area.
    Message Stream
    #rows - 1
