Quote Site Blocksize Declaration and other FTP Settings in FTPS or SFTP

I've been working on a project to convert old uploads from FTP to FTPS or SFTP.

I'm trying to replicate these commands:

I've been looking into it for a while now and can't see of a way using SFTP or FTPS that will allow these commands or maybe I'm just not understanding the syntax.

Does anyone know how to replicate these commands in either SFTP or FTPS?

Those are proprietary commands of your FTP server (some IBM mainframe?). In FTPS, you execute them the same way as in FTP. Though WinSCP equivalent for ftp.exe quote command is call:

For SFTP, I believe that IBM mainframes uses hacks with retrieving directory listing using a special syntax (in WinSCP you would use ls command).
See for example <invalid hyperlink removed by admin>
But I do not know details. You better contact a support of your mainframe server.
