Core RPG, Subfiles, and Externally Described Files

• Use externally described database, display, and printer files in a program
• Use EXTFILE.EXTMBR and OPEN/CLOSE operations in a program
• Create and maintain subfiles and programs that use those subfiles (DDS and RPG)
• Interpret subfile keywords (e.g., SFLCRRRN, SFLDSP, SFLDSPCTL, SFLDROP, SFLPAG, SFLFOLD, SFLRCDNBR, SFLEND,SFLNXTCHG.)
• Recognize appropriate use of RPG creation commands (e.g., CRTxxxPGM, CRTxxxMOD, CRTPGM, CRTBNDxxx)
• Use basic array handling (e.g., *IN, LOOKUP, SORTA, MOVE, MOVEA, indexing)
• Code and use figurative constants (e.g., *LOVAL, *HIVAL, *ALL, * BLANKS, *ZEROS, *ON, *OFF)
• Code and use job date and system date
• Code and use structured operations codes (e.g., DO, DOU, DOW, IF/ELSE/ELSEIF, SELECT/WHEN, EXSR, FOR/ENDFOR)
• Code and use structured operations codes with expressions (+,-,*,/,**,<,>,=,(), and, or, not)
• Code and use date data types and arithmetic operations, including date operations in expressions
• Code and use RPG IV built-in functions
• Use H-Spec keywords
• Use RPG IV OpCodes (e.g., Arithmetic, Date, Message, Array, Declarative, File, Branching, String handling, Structured programming, compare, initialization, subroutine, data area)
• Code and use D-specs, including keywords

ILE

• Explain, create and use Binding Directories
• Differentiate bound procedure calls from dynamic program calls
• Differentiate “bind by copy” from “bind by reference” and their appropriate uses
• Determine appropriate use of activation groups, including ILE and non-ILE
• Create and use Service Programs
• Determine the impact and appropriate use of the DFTACTGROUP (Default Activation Group) parameter on the CRTBNDRPG (Create Bound RPG) command
• Determine causes and ways to avoid Signature Violation errors when using Service Programs
• Determine the appropriate use of the scoping parameters for Override and Open commands such as OPNDBF and OPNQRYF
