for .. in .. , keyword
for X in T.X offers a simple iteration mechanism over the values of a specified vector. Unlike
each blocks, there is no diagram, no observation table, etc.
This mechanism allows to cross a table with itself, as illustrated by:
table T = extend.range(5) T.S = for N in T.N return N * sum(T.N) when (N < T.N) show table "" a1b5 with T.N, T.S
Several tables can be used as long as the common table exists and is unique:
table T = extend.range(5) table U[u] = by T.N mod 2 T.S = for tn in T.N, un in u return un + tn * sum(T.N) when (tn < T.N) show table "" a1b5 with T.N, T.S
