Build the Project

Before you build the project, change the contents of program1.pli to:

/* Micro Focus Open PL/I Console Application */
 
 program1: proc options (main);
   dcl sub entry;
   dcl a1 char(14);
   put skip list ('Hello world - main' );
   call sub();
   put skip;
   get list (a1);
   
 end program1;

On the menu bar, click Build > Build Solution.
Note: If, while going through the tutorial, you have already built the project, then you need to click Rebuild Solution instead of Build Solution (Build Solution only compiles the files that have changed and Rebuild Solution first cleans all generated files and them performs a clean build of the project).
