[esp-r] Re: sed

[Gian Luca Brunetti]

Dear Achim and Arianna and list,
one consideration about the reliability of ESP-r for batch scripting. I 
think that it is more rock-solid when ESP-r is compiled for text mode 
and not compiled for graphics (then launched with the -text mode 
option). I don't know were the difference lies. I have noticed that the 
two behaviours are not identical.

Best regards

Gian Luca Brunetti
