The GNU Awk User’s Guide: 8.1.6 Using Predefined Array Scanning Orders with gawk

[Walter Bächi]

Hi

The following example is wrong:

   /… if ("sorted_in" in PROCINFO) { save_sorted =
   PROCINFO["sorted_in"] PROCINFO["sorted_in"] = "@val_str_desc" # or
   whatever } … if (save_sorted) PROCINFO["sorted_in"] = save_sorted /

It should be:

   /… if ("sorted_in" in PROCINFO) *save_sorted =
   PROCINFO["sorted_in"]****PROCINFO["sorted_in"] = "@val_str_desc"**#
   or whatever* … if (save_sorted) PROCINFO["sorted_in"] = save_sorted /

Otherwise it is useless aslong as/"sorted_in"/  is not defined before 
in/PROCINFO/.
