The let tag: is a new tag that lets you create blocks like: * = Which yields: 1 * 0 = 0 2 * 1 = 2 3 * 2 = 6 4 * 3 = 12 The #let tag works like the #with tag, but is more flexible in that it allows you to make multiple assignments, and allows you to chain assignments, using earlier declarations in later assignments. Notice inthe ablove example, the 'result' variable is based on 'num' and 'index', both of which are assigned in the same #let expression. Syntacticly, each argument to be evalulated in the head of the let tag must be seperated by a newline. Enclosing an argument in double quotes causes it to be evaluated by the DTML expression machinery. Un-quoted arguments are referenced by name. Evaluation is in sequence with the result of earlier assignments available to later ones. Later assignments can also override earlier ones, which can be helpful for longer step-by-step calculations. The variables thus set are in effect for the life of the block.
