DFHTF0200 date time applid termid netname userid tranid Ipaddr ipaddr Mapset mapset Map map Field field Attr attr Invalid 3270 datastream from client

Explanation

The 3270 datastream received from a terminal emulator client attempted to override a protected field.

The field value returned in the DFHTF0200 message is a 3270 buffer address in decimal.This address represents the position of a field on the screen, 0 being Row 1 Column 1 and 1919 being Row 24 Column 80 for a 24X80 display image screen size.

The field value can be converted into Row/Column using the following method below (where W is the column width of the display screen):
  • (Field value / W) + 1 = Row number
  • The remainder + 1 = Column number
For example, given a display image of 24 rows and 80 columns the Row/Column of FIELD value 1602 is:
  • (1602 / 80) + 1 = Row 21
  • (1602 -(20 * 80)) = 2 + 1 = Column 03

The attr values returned are:
