Sanko was a short utility by ChaRleyTroniC which added a new command, SANKO, to Protext. This would save the current Protext document in RTF (Rich Text Format), ready for transfer to a PC. Most formatting was retained.
Though simple in outlook, the tool proved useful for many - principally members of WACCI - who were transferring from a long-serving CPC to a PC or Mac environment. WACCI editor John Bowley used it for a long while when receiving contributions written on CPCs.
