Section 3 - Core RPG (15%)

Recognize appropriate use of RPG creation commands (e.g., CRTxxxPGM, CRTxxxMOD, CRTPGM, CRTBNDxxx)

  • CRTxxxPGM
    • Used for compiling a RPG ILE 4 program without the "NOMAIN" H-Spec
  • CRTxxxMOD
    • Used for compiling a RPG ILE 4 program with the "NOMAIN" H-Spec
  • CRTPGM
  • CRTBNDxxx

Define basic arrays (e.g., compile time, pre-run time, run time) using D specs

Use basic array handling (e.g., *IN, LOOKUP, SORTA, MOVE and MOVEA, indexing)

Code and use figurative constants (e.g., *LOVAL, *HIVAL, *ALL, *BLANKS, *ZEROS, *ON, *OFF)

  • *ALL
  • *BLANKS
  • *HIVAL
  • *LOVAL
  • *OFF
  • *ON
  • *ZEROS

Code and use job date and system date

Code and use structured operation codes (e.g., DO DOUxx, DOWxx, IF/ELSE/ELSEIF, SELECT/WHEN, CASxx/EXSR)

Code and use structured operation codes with expressions (+, -, * ,/, **, <, >, =, (), and, or, not)

Code and use date data types and arithmetic operations, including date operations in expressions

Code and use SDS

See Program Status Data Structure
