LDPL was designed to be a rigidly structured programming language and, as such, variable declarations and the rest of the code procedure are separated in two different, mutually exclusive sections within a source file. Variable declarations should be placed within the DATA section, while the rest of the code should be placed inside the PROCEDURE section. Further subprocedures should be placed also within the PROCEDURE section, inside their own SUB-PROCEDURE subsection.
Bearing this in mind, the basic skeleton of a LDPL source code will look like this:
Every statement in LDPL has to be on its own line. Thus, statements are separated by line breaks and it's not possible to have two statements on the same line.
