[vcf-midatlantic] 1970's TV show that taught FORTRAN ?

Looking to settle an argument... I remember there was once a TV show that taught FORTRAN programming. This would have been the mid-1970's and I think it was broadcast over WNET channel 13 (NYC metro area PBS) in the afternoon. I can't have been the only one to have seen it, but I'm unable to find anything about it on the net. Reply to the list. TIA, Andy
