A VLIST is similar to a LIST, but has no associated type (it does have a character type for its names) thus a VLIST statement may look like this:
VLIST*8 WZE
declaring WZE a list of pseudovariables with names of up to 8 characters. However, instead of the list also containing the values of these pseudovariables within itself, this time each pseudovariable is also a real variable, and the VLIST contains information linking each name to the variable to which it corresponds.
