The EACHMULTI loop allows you to process a set of variables that have the same name, one at a time:<% EACHMULTI $sections$ %> ... Inside the loop, $sections$ is set to one instance of the SELECT NAME="sections" input. ... The loop continues as many times as there are inputs with that name. <% ENDMULTI %>EACHMULTI was originally designed specifically for processing SELECT MULTIPLE inputs, but it works for any other type of inputs that have the same name (e.g. you could put a table of text input fields in a form that all have the same name). It also works with a list of variables (e.g. <% EACHMULTI var1, var2, var3, ... %>), which will let you work with the first instance of each variable inside the loop, then the second instance of each, etc., so you could define a two-dimensional table of inputs in a form, with columns of variables that all have the same name. The SETMULTI command lets you set multiple instances of a variable (i.e. each time it is used, it creates a new variable with the same name instead of resetting the value of a single variable, as SET does). The variables set with SETMULTI can then be processed later with an EACHMULTI loop. This gives the basic functionality of array processing without using subscripting.
