# hi Arnold,

# 

# 

# Please try the script beneath...

# I'm not sure if this is a bug or not, but I would expect 

# the empty string as an array index just to be treated 

# like any other string

# 

# so if ("" in ta) would be true, and for ( i in ta ) should loop only once.

# 

BEGIN {

        v=""

        ta[v]++

        if ( v in ta) print "a",v,++ta[v],ta[v]

	print "b",v,++ta[v],ta[v]

        for( i in ta) print "c",++c,i,ta[i]

} 

# 

# goodluck, Eiso
