(PCICNT)
represents a user-defined field used to accumulate the count of recursive
errors. It should be in the process control information (PCI) area of the TCTTE.
SYSTEM COUNT
(TCTTENI)
represents the 6-byte field in the TCTTE that contains the terminal input and
output counts (TCTTENI+TCTTENO). In the example, these two adjacent fields
are considered as one 6-byte field.
Because this example requires access to the TCT terminal entry (TCTTE) to
examine the SYSTEM COUNT and to locate the process control information (PCI)
area, the DFHTCTTE symbolic storage definition is included so that fields can be
symbolically referenced.
