No matter how carefully you code you will from time to time find that your MapBasic code will not compile. When this happens you will have one or more messages appear at the bottom of the MapBasic Development Environment window. Some of these messages are self explanatory. For example, you have failed to initialise a variable or have not included the necessary definition files. You also need to be aware that, even though your code may compile, because of logic errors it still may not perform in the way you intended. In the previous blog Creating a simple MapBasic program the code had no errors and would have compiled and run as intended.
Below is code but containing a few errors. If we try to compile this code it will generate a number of error messages. On this occasion I would suggest you copy and paste this code into MapBasic if you are not familiar with correcting coding errors. Normally I would always recommend typing coding samples, as you learn more through that method. However, on this occasion copying and pasting is the correct procedure.

Program: SimpleCodeExample with errors
Purpose: Show the note, print and loop facilities
' Declare
Declare Main
' Function: Main
' Purpose: Loop five times and print out a message each time
' Shows how the print, note and loop statements work
Sub Main
i As Integer
' the loop will execute a Print statement 5 times
For i = 1 to 5
Print "Hello world! The count is now " + Str$(i)
Next
' Let the user know that looping has finished
Note The loop is now finished."
End Sub
