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.
