Did you lookup the ALTER command parameters (TSO HELP ALTER)?

The help text shows that you can enter the command:

TSO ALTER 'entryname' RECORDSIZE(average maximum)

where

'RECORDSIZE' - Specifies the average and maximum lengths, in bytes, of the records in the data component.

'average' - Average length of the records in the data component.

'maximum' - Maximum length of the records in the data component.

Now, common sense would indicate that this option is restricted to VSAM KSDS file structures.
