Using FOR EACH statements to retrieve records for a table and NO-LOCK to read records without locking them
Using the MESSAGE statement to display messages
Using the PAUSE statement

Using the EXPORT, PUT, and IMPORT statements
Conventions for Progress Syntax in Class
To highlight Progress syntax, the following conventions are used in the examples in this course:
Progress keywords are shown in upper case for emphasis in the code. However, Progress is not case sensitive. The QAD standard in source code is to use all lower case.
Table and field names are shown in lower case.
Character strings are surrounded by quotes (" ").
Square Brackets ([]) indicate optional items.
Ellipses (…) indicate an item may be repeated.
