Program too big to fit in memory error

[Angus Comber]

Hello

I am running this command:

esnacc.exe _C -d csta2.asn1

and getting error:
Program is too big to fit in memory

I am running version 1.6 of eSNACC and operating system is Windows XP.
About 600MB free memory when run command.

The asn1 file is 83k in size.

What can I do?

Angus
