Coding rules for CLP Commands

These rules apply both on Command Line and inside a CLP program.

  • Blank space separates parts of a command
    • Example WRKOUTQ QFISCAL* to get at list of all OUTQ whose name starts with QFISCAL
  • Parentheses go around keywords and values
    • Example SAVLIB LIB(XFILES} DEV(TAP01)
  • Slash connects parts of a qualified name or path name
  • Single apostrophe indicates beginning and end of a quoted character string (a constant)
    • Example SNDMSG MSG{'Intruder Alert'} TOUSR(QBOSS)
  • *N is a place holder (take the defaults) indicating the absense of a positional parameter
    • Example RUNQRY *N LOG
  • Predefined values begin with an asterisk and indicate IBM-defined values which are reserved by OS/400 and may be used in programs to have those set functions
    • Example SAVLIB LIB(*ALLUSR} DEV(*SAVF)
  • Generic name contains one or more characters that are those that start some object(s) then end in asterisk to signify wild card list of all that share that prefix
    • Example DSPF*
