[comp.lang.prolog] sbprolog problem

dennis@boulder.Colorado.EDU (Dennis Heimbigner) (10/29/87)

I am having a problem  starting up sbprolog on $readloop.
It dies in strlen with a null string pointer.
Using dbx, it appears that b_TRIMBUFF is at line 328, which is:

    if (len<0) len = strlen(get_name(ptr));

The problem is that ptr->name is nil.
Any idea what is going wrong?
I am running  on a vanilla sun 3/75 using SunOS 3.2.
