TUTSTACK <new_tutstack> initiates the tutstack. TUTSTACK (without any parameters) displays the contents of the tutstack on the next edit line. Example: TUTSTACK 11@SURVO MM@Data1 initiates the tutstack with words W1=11, W2=SURVO MM, and W3=Data1. Thereafter activating of TUTSTACK without parameters gives on the next line: 11@SURVO MM@Data1@ . The TUTSTACK command is useful when testing new sucros. One can initiate and read it for further examination. M = More information on the sucro memory S = General information on sucros
