[developers] MRS variable naming in recent cheap (LOGON)

[Berthold Crysmann]

Dear all, 

I have spotted some mysterious behaviour with  the recent version of
cheap coming with the LOGON branch: if used without the -t switch, event
variables are output as variable type i (see below), with the -t switch,
however, they surface as "e" (see below). 

It seems that both GG and ERG (but not TERG) are affected. 

What is the reason for this? Is there a quick fix?

Thanks for your help. 

Best, 


Berthold
