Writing to a custom developer's trace file

Question

Is it possible to create a custom dev trace file and write to it from a custom abap program?  We've developed a custom ABAP program and we'd like to write errors to a custom dev trace file that can be monitored in ST11.  I know we can write to the SLOG using FM RSLG_WRITE_SYSLOG_ENTRY, but I don't want to fill up the SLOG in transaction SM21.  I'd rather write to a custom log file in ST11.  Is it possible to create your own dev trace log file?
Thanks,

OK, I was able to get it to compile, but it does not write it to the log in SLG1.  There are no error message when it runs.  Sy-Subrc = 0.
DATA: go_msglist        TYPE REF TO if_reca_message_list.
  data: gs_msg type RECAMSG.
  DEFINE mac_build_msg.
    clear: gs_msg.
    gs_msg-msgty = &5.
    gs_msg-msgid = 'ZZ'.
    gs_msg-msgno = '000'.
    gs_msg-msgv1 = &1.
    gs_msg-msgv2 = &2.
    gs_msg-msgv3 = &3.
    gs_msg-msgv4 = &4.
    gs_msg-detlevel = &6.
  END-OF-DEFINITION.
  go_msglist = cf_reca_message_list=>create( ).
  mac_build_msg 'MyMessage' space
                 space space 'I' '1'.
  go_msglist->add( is_message = gs_msg ).
