Discrepancy or a bug? #22

spitbol doesn't print anything while both bunde's csnobol4 and berstis' snobol5 print 3.

Discrepancy or a bug?

CheyenneWills commented 1 year ago

Not so much a bug, but there was a commit a while back that changed the default for &anchor from 0 to 1.

If you switch to unanchored mode (e.g. &anchor = 0), your test fixes the problem.

I will revert the default so that:

1) it is consistent with the other implementations 2) matches the last "pdf" documentation for SPITBOL.

I've pushed a development branch hopefully fixes this. See the commit "Restore default value for &anchor to 0" should address the problem.

I'll be asking some folks to test this branch before promoting it to the main branch.

The issue is fixed. Thank you.
