• Section E.2, "Flows."

E.1 Subroutines

Using subroutines:

• Allows for standard names to make program maintenance easier.

• Launch primarily from Mainline.

The following table includes internal RPG subroutines within JD Edwards World programs:

Subroutine	Description
S00EX	Processes all function exits. Choose a function exit and the system launches one of the following programs: Display Functions (F24) to launch P9601H Field Sensitive Help (F1) launches X96CCX. After X96CCX launches, the system launches subroutine S00VL. Display Error Message (F7) launches P0000E HELP launches P00HELP Clear Screen (F22) launches subroutine S001 Launches all programs to process all user defined function keys
S00VL	Retrieves values with Field Level Help. After X96CCX launches, the system launches subroutine S00VL.
S00OP	Subfile Options.
S001	Clears all database and screen fields. This usually only clears key fields and VC0 fields if you choose Clear Screen (F22).
S002	Checks for level breaks for reports. Activates level break markers. Retrieves the total line description
S003	Validates the key fields. Launches subroutine S998 if the system invokes auto inquire. Sets the file pointer. Performs a SETLL and CHAIN if the program is a single record maintenance program Performs a SETLL for subfile programs Launches subroutine S004 to load screen and report fields Monitors that subfile records load if this is a subfile Loads subfile records that the system does not use with blanks
S004	Display and load the screen or report fields.
S005	Scrubs and edits screen and report fields. Moves screen data to database fields Activates error indicators if a field value is in error Updates records in the database file if this is a subfile Updates the subfile
S010	For reports with level breaks it: Prints the total Clears the level break totals Prints the grand total when it reaches the end of the file Prints the detail Adds to the new level break totals Launches subroutine S020 if this is a report with subheadings If this is not a report, S010 updates, adds, or deletes records from the database file. Deactivates the Clear Screen (F22) function and executes S001 to clear the buffer before reading another record.
S020	Print Report Subheadings.
S998	Loads Data Dictionary values, one time only. Retrieves row description for level breaks and subheadings, if applicable.
S999	Housekeeping, one time only. Sets auto inquiry Defines key lists Retrieves processing options and level breaks, if applicable Retrieves vocabulary overrides Loads error messages Opens file Retrieves the current date Defines work fields using *LIKE Prints cover page and Helps in a report
