Ü   RTVMBRD

In the following CL procedure, a RTVMBRD command retrieves the description of a specific member. Assume a database file called MFILE exists in the current library (MYLIB) and contains 3 members (AMEMBER, BMEMBER, and CMEMBER).


    DCL  &LIB      TYPE(*CHAR) LEN(10)
    DCL  &MBR      TYPE(*CHAR) LEN(10)
    DCL  &SYS      TYPE(*CHAR) LEN(4)
    DCL  &MTYPE    TYPE(*CHAR) LEN(5)
    DCL  &CRTDATE  TYPE(*CHAR) LEN(13)
    DCL  &CHGDATE  TYPE(*CHAR) LEN(13)
    DCL  &TEXT     TYPE(*CHAR) LEN(50)
    DCL  &NBRRCD   TYPE(*DEC)  LEN(10 0)
    DCL  &SIZE     TYPE(*DEC)  LEN(10 0)
    DCL  &USEDATE  TYPE(*CHAR) LEN(13)
    DCL  &USECNT   TYPE(*DEC)  LEN(5 0)
    DCL  &RESET    TYPE(*CHAR) LEN(13)
    .
    RTVMBRD    FILE(MYLIB/MYFILE) MBR(AMEMBER *NEXT) +
               RTNLIB(&LIB) RTNSYSTEM(&SYS) RTNMBR(&MBR) +
               FILEATR(&MTYPE) CRTDATE(&CRTDATE) TEXT(&TEXT) +
               NBRCURRCD(&NBRRCD) DTASPCSIZ(&SIZE) USEDATE(&USEDATE) +
               USECOUNT(&USECNT) RESETDATE(&RESET)

The following information is returned to the procedure:

·         The current library name (MYLIB) is placed into the CL variable name &LIB

·         The system that MYFILE was found on is placed into the CL variable name &SYS (*LCL means the file was found on the local system, and *RMT means the file was found on a remote system.)

·         The member name (BMEMBER), since BMEMBER is the member immediately after AMEMBER in a name ordered member list (*NEXT), is placed into the CL variable named &MBR

·         The file attribute of MYFILE is placed into the CL variable named &MTYPE (*DATA means the member is a data member, and *SRC means the file is a source member.)

·         The creation date of BMEMBER is placed into the CL variable called &CRTDATE

·         The text used to describe BMEMBER is placed into the CL variable called &TEXT

·         The current number of records in BMEMBER is placed into the CL variable called &NBRRCD

·         The size of BMEMBER's data space (in bytes) is placed into the CL variable called &SIZE

·         The date that BMEMBER was last used is placed into the CL variable called &USEDATE

·         The number of days that BMEMBER has been used is placed into the CL variable called &USECNT The start date of this count is the value placed into the CL variable called &RESET
