naming scheme of i5/OS commands

This post is a citation from http://www.mcpressonline.com. I like it because this tip helps me to remember command set from i5/OS. I cite it to my blog here as I think this place is better than my Web browser bookmark.

1. First, a three-letter abbreviation for a verb, such as create, remove, print, or send. See the table below.
2. Last, a series of abbreviations for modifiers, such as file, program, job queue, or user profile. These abbreviations are usually three letters long, but there are many exceptions.

Example Abbreviations
Verbs		Modifiers
CRT	Create	F	File
CHG	Change	PF	Physical File
DLT	Delete	LF	Logical File
ADD	Add	SRCF	Source File
RMV	Remove	CLPGM	CL Program
DSP	Display	RPGPGM	RPG Program
WRK	Work with	MSGQ	Message Queue
STR	Start	OUTQ	Output Queue
END	End	JOBQ	Job Queue
		DTAQ	Data Queue
		DTAARA	Data Area
		SBS	Subsystem

For example,

DSPSBSD SBSD(QUSRWRK) => DSP+SBS+D(display)
STRSQL  =>  STR + SQL 
WRKJVMJOB  =>  WRK + JVM  + JOB
CRTDTAQ  => CRT  +  DTAQ
DSPMSGD CPEnnnn (where NNNN is 4-digit error number)
CHGATR OBJ(Sth) ATR(*READONLY) VALUE(*NO)
WRKLNK 'your/file'
