Compiling and running a program

Task Manager toolbar

The DPL Task Manager contains powerful compilation and debugging tools.
These tools enable the programmer to check the program in great detail.
Some of the debugging tools are automatic and check for programming
errors.   Others allow the programmer to check the program line by line to
verify the logic of the program.

Compiling a program

1

Save the written program as a

.

DPL

file.

2

Click on

(Compile

Compile), or to compile and download the program

automatically, click on:

The Compile...

Compile... dialog box appears.

Normally the options can be left as they are shown. In this case, to continue
the compilation process click on:
