Stoyanova, B. Botev, R. Gospodinov Experiments with the XCTL system

WSSEERE Meeting Ohrid, August, 25th - 30th, XCTL activities in the DAAD project BelgradeBelgrade –Applying URCA method to XCTL –Realized with special version of XCTL: Ported to Win32Ported to Win32 Using environment simulation, onlyUsing environment simulation, only –Successful application was possible

WSSEERE Meeting Ohrid, August, 25th - 30th, XCTL activities in the DAAD project Novi SadNovi Sad –Translation of requirements specification for use case Manual Adjustment –By now version 2.2 available –Very useful as a starting point when dealing with XCTL for the first time
