Getstats uses a hash, %globals
, to maintain a global environment. Any
variable that is defined in %globals
is replaced under Global
replacement.
When evaluating two related expressions, Getstats declares the Perl hash
%ptemp
. If a variable is defined in %ptemp
, it is also
replaced under Global replacement. For more information See Temporary Variables.
Getstats defines several global variables automatically:
file
fileno
filecount
The following global variables are set or used by Getstats default library:
confidencelevel
delimiter
spacing
precision
wraised
The global variables colexpr, stathashes, outcols, agg_commands, and agg_threads are complex types. To modify or read them them more knowledge is required, and you should look in the corresponding manual section.
