| The program with the .html extension can be saved as .cbl and then opened in the COBOL compiler. The PRE or the HTML PRE and the /PRE or the /HTML /PRE (note there are greater than and less than symbols around these commands) have to be deleted before compiling. The program with the cbl can be loaded into the compiler but you will see a symbol that looks like a music note which is the carriage control. These usually are not a problem unless you make changes and then you have to delete them. | |
