_DATA_EXCHANGE_
The Compilation Option _DATA_EXCHANGE_ is required whenever a Kernel requires Data exchanges with the Terminal (see Section 5.9.2 of EMVCo Book A v2.10)
The Data Exchange mechanism may be used for:
Checking Exception File
Requesting Missing Data
Processing Data Storage Information
…
This Compilation Option is use by Kizis and AgnosSP to initialize the Data Exchange Buffer
Absence of this Compilation Option reduces RAM consumption by ~20K
