A programming error that causes a program to behave in a manner not intended by the writer 
of the program is called a “bug”. Finding and eliminating such errors is called “debugging the 
program”. 
Any of the following conditions can indicate that your program has a bug and requires 
debugging. 

• If an error message appears when you try to save the program 
• If an error message appears when you try to run the program 
• When a program produces some abnormal or unexpected result 

When an error occurs, a dialog box appears to explain the cause of the error. Carefully 
read the text of the error message and then tap its [OK] button. This closes the dialog box 
and positions the cursor on at the location where the error occurred. Make the necessary 
corrections in accordance with the explanation provided by the error message. 

•  If the cause of the error cannot be specified for some reason, tapping [OK] on the error message 

dialog box displays the Program Loader window, without positioning the cursor at the location of 
the error. 

•  In the case of a program for which editing is prohibited (a program for which “EXE” is indicated 

as the variable data type), tapping [OK] on the error message dialog box displays the Program 
Loader window, without positioning the cursor at the location of the error. 

If execution of a program produces unexpected or abnormal results, carefully read through 
the program and correct errors as required. 
The following commands can come in handy when debugging a program to locate 
unexpected results. 

Move the cursor to the beginning of the program
