Except for the name, which IIRC was an intentional dig at an early COBOL standard that defined how you pronounced 'COBOL'. 'SNOBOL' can sound like 'snow-ball', analogous to a US accent where COBOL can be pronounced 'CO-ball'.
[Edit] I used SNOBOL briefly in the 80s at Uni. It was one of the first 'odd' languages we were introduced to after Pascal, along with APL.
I think the accents here were exaggerated for comedic effect. You are a right, I’m a Brit and would personally pronounce the ‘BOL’ to sound like ‘doll’ rather than ‘ball’. Unfortunately I can’t now find a reference to the original standards
SNOBOL was a one-of-a-kind pattern matching language at the time. Now there are lots of them, or rather, lots of regular expression features.
It had nothing whatever to do with COBOL.
