SSI format versioning between 4.0.1 and 4.0.2

Guest · Thu Jul 09, 2015 4:59 am

Hello,
Wondering if someone could point me towards documentation for changes to the SSI format.

When reading in an SSI file created in 4.0.2 into 4.0.1 I get the error

Code:

incompatible versions of ssi: 8/526 vs 8/528

When I write this file back out and compare the two files, they differ only by the first line:

Code:

1c1
< 98 8 528 100663424 10321
---
> 98 8 526 100663424 10321

I guess there is no significant difference between SSI format versions (?) 8/528 for Singular 4.0.2 and 8/526 for Singular 4.0.1 but I'd appreciate some help confirming this, or at least interpreting this first line of the file. Regards,
Eric

The basic data representations (int, string, number, poly, ideal, etc.)
are the same. But calls to kernel commands differ:
there are 2 new (http://www.singular.uni-kl.de/Manual/4- ... tm#SEC2400) .
First line:
98 <ssi-version> <max. token> <current options, part 1> <current options, part 2>

Summary: as long as no "quote" is used, the format is the same.
