Add -g & -keep to the c4gl commandline when compiling the app so that
you have debugging information and you will be able to debug the 4GL
program using any system debugger (you'll be looking at the generated
.ec source but the 4GL will be in comments so it's not hard to debug if
you are used to debugging C source code).

That said, make sure that the window you are running in is at least 77
characters wide and 21 lines high (two lines for the 4GL message and
prompt lines). Also make sure that the FORM you've create will actually
FIT in 19 rows by 77 columns when you allow for the two lines and two
columns for borders.
