Details about these tag types, how they are used, and the format of the data that is included in them is detailed in the following sections.
Note: Fields passed in the data stream is by the offset of that field on the screen being processed. Valid values for data offsets are between 2 and 1920 (for 24 by 80 screens) and between 2 and 3564 (for 27 by 132 screens) and are always generated as 4-character strings with leading zeros where applicable. Thus 1047 and 0043 are valid offsets, whereas 2430 and 84 are invalid (value outside range (for a 24 by 80 screen) and no leading zeros respectively). The standard algorithm for converting between screen offset and screen row/column is:
OFFSET = ((ROW - 1) * maximum-columns) + COLUMN
Where maximum columns is either 80 or 132.
The YCVTRCO command can be used to convert between row or column and offset, and vice-versa.
Note: Within this document, where an offset value is defined within a tag description, it is represented as NNNN.
