S002 abends on VBS SMF TAPES

I read Dr Merrills entry that SAS has been able to fix S002 Issues since 1972(ish). Can someone share the (presumably short) SAS code to do so, please? A friend really had a tough time writing the assembler code to do so and will be crestfallen that SAS has been able to do so (for so long)

Re: Data volumes

It is not the exact power of 2 from 15 bits on. 2 **15 is 32767, but IBM only allowed 32760 cylinders. 2**16 is 64K, but IBM only allowed 65.520 cylinders. EAVs are a multiple of 1113 cylinders under 2 **18 then 2 **20 limits and eventually 2 **28, I listed the highest multiple. On Tue, Jun 11, 20

Re: Data volumes

The numbers of cylinders (column 2) that can be represented by the number of bits in column 1 are correct from 7 to 14 bits, but the table has slightly wrong values from 15 bits and higher.  And 7 of the values are odd numbers, which can never happen. Bill Fairchild Franklin, TN - O
