You can use the table menu to perform any of the following operations once you generate a
table.
• Change the values of variable
• Edit (delete, insert, and append) rows
• Delete a table
• Draw a connect type graph
• Draw a plot type graph
• {FORM} ... {return to Table relation list}
• {DEL} ... {delete table}
• {ROW}
• {DEL}/{INS}/{ADD} ... {delete}/{insert}/{add} row
• {G CON}/{G PLT} ... {connected type}/{draw plot type} graph draw
• •
• If you try to replace a value with an illegal operation (such as division by zero), an error
occurs and the original value remains unchanged.
• You cannot directly change any values in the other (non-
