JOB Reads information from files, examine and manipulate data, write information to files, and initiate printed reports. Creates sequenced or ordered files.
Data can be displayed to a terminal operator and received back into the program. Files can be read and updated. You can code one or more procedures PROCs at the end of each activity. Procedures are separate modules of program code that you use to perform specific tasks. The following table shows some CA Easytrieve keywords and other items in the sections where they are usually located.
The table gives the general order of CA Easytrieve statements in a program.
