A temporary program can be executed from the program editor (MCT10/APOSS), temporary programs are 

only stored in RAM and are thus lost at power-down. The temporary program can also be executed in a 

special Debug mode where it is possible to influence the program execution as well as reading out data and 
variables, see on-line help of APOSS for further details. 

When connecting a PC with MCT 10 to the drive, the active program might be aborted e.g. when 

downloading a new program or when working with the program editor ([Esc] will abort program 
execution). 

NB!:

In case of an error the active program will be terminated if no error handler (ON ERROR GOSUB 

xxxx) is defined and the program will not be restarted.
