Symbol $ in ABAP

[Former Member]

Hi All

This is my question :Which is the objetive to use $ symbol in ABAP sentences ??

For Example :

form maintain_list tables $list_rgdir structure list_rgdir
                   using  $hide_seqnr like list_rgdir-seqnr
                          $clicked_seqnr like list_rgdir-seqnr
                          $hide_persnr like hide_persnr.

  data: selected_persnr like hide_persnr.
  selected_persnr =  $hide_persnr.

  do.
    clear:  $hide_seqnr, $hide_persnr.
    read line sy-index.
    if sy-subrc ne 0.
      exit.
    endif.
    check not  $hide_seqnr is initial.
    read table $list_rgdir with key seqnr  = $hide_seqnr
                                    persnr = $hide_persnr.
    if sy-subrc = 0.                             
      $list_rgdir-selec = sy-lisel+1(1).         
      if  $hide_seqnr = $clicked_seqnr .
      and $hide_persnr = selected_persnr.        
        if list_rgdir-selec = ' '.              
          list_rgdir-selec = 'X'.
        else.
          list_rgdir-selec = ' '.
        endif.
      endif.
      modify $list_rgdir index sy-tabix.

SAP sometimes uses "$"fields to denote subroutine parameters or temporary fields.I don't think they have any other significance other than naming convention.

[Former Member]

yes. that's correct - they're just normal variables SAP uses in their programs - I think they have veered away from using naming conventions like that, and are adapting more standard naming convention lately.

Hi Gregory,

I think there is no special significance to $ symbol in ABAP sentences. I thought he/she may be used to different these $ variables apart from the other variables used in subroutine and $ variables are ONLY paramet variables.

hiii

here $ represent as variable name only.because there is no any special use of this character in abap.so its just a name of variable to show it different from others.

reward if useful

thx
