of a loop. #!N #!N Syntax This module has no inputs.

TAB #!EF #!N #!N Functional Details #!N #!N The output on
the first iteration of a loop is 1 (one), and on
all subsequent iterations 0 (zero). #!N #!N Typically, loops are initiated
with ForEachMember or ForEachN, although they can also be implemented with
a Get/Set pair and Done. First is often useful for resetting
the GetGlobal tool at the beginning of a loop. Note that
if GetLocal is used in a loop, First is unnecessary. Note:
If this module is used in the scripting language, the results
are defined only if they are used inside a macro. #!N
