When an awk program ends because of a call to exit(), the exit status is the value
passed to exit().
Most constructions in this implementation of awk are dynamic, limited only by
memory restrictions of the system.
The maximum record size is guaranteed to be at least LINE_MAX as returned by
getconf. The maximum field size is guaranteed to be LINE_MAX, also.
