about loop "for (var in tab)"

[xuenylom]

i need to check variables from a array (they are set as index)

i know how to proceed when the variable is index in the array, but what is the syntax for variables NOT index in the array?

is it:

--------------
for !(var in tab)
---------------
?

thx a lot

No, all arrays in awk are associative. See Sed & Awk Chapter 8.4 Arrays
