Reportmachine two-time report usage

Reportmachine two-time report usage

Many people have used reportmachine, which is a very powerful report production tool and I am also using it. When I made a report, I wanted to display the total number of pages. It prompted me to use the report twice. I didn't know how to use the report. Then I searched the report online, this requires you to set the doublepass attribute to true.

If the loadfromfile method is used to load the report file
Doublepass: = true;
It must be loaded. Because the report does not know the total number of pages for the first time, it needs to be printed and calculated in advance. This is two times in total, so that the total number of pages can be printed.
