It wold be interesting to know if using sftp command line (from ssh), it will work.
cmd exemple: sftp -P 22 userid@serveur_domain:/remote_dir
If it works, than I'll check if pipe mode is usable under rexx and if yes, a simplified GUI could be quickly created ...
updt: For secuyrity raison, psw can't be sent through pipe not put into a batch file.
I give a try using copy/paste and it works ! but how to issue a command (e.g. rexx) to have the "paste" operational into a specific cmd prompt window under which sftp is started ?
