-general: what is the database

We have to tell gd1.pp where the results of our run of gd1 are stored. We tell gd1.pp this in its section -general. We can specify the name of the resultfile in two ways: By writing out the name of the file:

 -general, infile= /tmp/bruw1931/garbage/doris

or by using the special name @last:

 -general, infile= @last

When we use @last, gd1.pp looks up the name of the last resultfile in a special file $HOME/name.of.last.gdfidl.file. This file is written by every run of gd1.

By the way: Both gd1 and gd1.pp understand almost all their commands also when they are abbreviated. So we may tell gd1.pp to take the last resultfile eg. as follows:

 -ge, i @last
