  • clear data structure array

    Hi guys,

    i have a problem with the data structure.
    is there anyway to clear the data structure array without
    looping the program with ocur???
    just one step just usual array.


    Code:
    I  DSDT        DS                         99              
    I                                            1  22 #DT1  
    I                                            1  110#DSACC
    I                                           12  13 #DSKDW
    I                                           14  220#DSNOW
    
    it just a simple coding like this :
    
    C   2         OCUR    DSDT           
    C              MOVEL  'TEST'    DSDT 
    C   1         OCUR    DSDT           
    C              CLEAR   DSDT           
    C   2         OCUR    DSDT           
    
    when i clear the DSDT, it only clear the data structure in occurence 1,
    is there anyway to clear all the DS without looping like this :
    
    C           Z-ADD1  $X      4 0
    C     $X  DOWLE  99
    C     $X  OCUR     DSDT
    C           CLEAR    DSDT
    C           ADD       1       $X
    C           ENDDO
    ???? any simple way like clear array? or function that i don't know maybe?

    Thx u

      Re: clear data structure array

      Well the first point to note is that you _don't_ have a DS array in your code - you have a multiple occurence DS (MODS) which is not the same thing. When you use a MODS - as you have noticed - you can only access (and therefore clear) one element at a time _unless_ you specify *All as Factor2 - in this case all elements are cleared.

      MODS are effectively deprecated with the advent of DS arrays in V5R2. Simply define DIM(...) on the DS definition line to define one. With these a CLEAR will always work on all elements.

        so cannot clear all the Data Structure at once?
        if can, would u give me the example...
        right now i just using the RPG III, i'd like to use the rpg iv, but
        cannot do that, because of the project use the rpg iii.

        Thanks

            oohh i think i get it, it seems the syntax only works in RPG IV. But now
            I am working on RPG III.
            BTW Thx guys

              Sob!

              Why oh why is anyone still using RPG III !!

              The bl**dy thing has been obsolete for over 12 years! Isn't IBM saying that the S/36 and S/38 compilers are becoming a PRPQ after V5R4 enough writing on the wall to warn people to stop wasting their money!!!

                Count your blessings where they lie... at least it wasn't RPGII, using IDDU and OCL!

                    Ewwww..... How bout RPGIII with member types of RPT? You never knew what copy book was for what part of the source.

                    Grandpa, can you make the dinosaur run across the screen again???

                    Ha ha ha ha ha ha ha!

                           /end-free
                          Note: Clear *All and Reset will the numeric fields in the MOD to *Zeros and the For loop will set the values to *Blanks.
