Multiple Response variables are essentially Categorical Arrays in which one or more categories are set as "selected". These methods allow you set that state.

Categories or a Variable subclass that has Categories
For the dichotomize methods, the numeric or logical indices
of the categories to mark as "selected", or if character, the Category
"names". Note that unlike some other categorical variable methods,
numeric indices are positional, not with reference to category ids.
Categories or the Variable, (un)dichotomized accordingly
dichotomize lets you specify which categories are "selected", while
undichotomize strips that selection information. Dichotomize converts
a Categorical Array to a Multiple Response, and undichotomize does the reverse.
