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
