      ATTACH  process-name

1  –  Parameters

1.1  –  process-name

    Specifies the process to which control passes. The process must
    be an existing process. If the process name contains blanks,
    lowercase characters, or other special characters, enclose the
    name in double quotation marks (" ").

2  –  Description

    The ATTACH command passes control from the current process to a
    parent process or a subprocess.

3  –  Examples

    1.CDO>  ATTACH JIM SMITH
      $

      In this example, the ATTACH command passes control from the
      current parent process at the CDO prompt to the JIM SMITH
      subprocess at the system prompt.

    2.CDO>  ATTACH "Jim Smith"
      $

      In this example, the ATTACH command passes control from the
      current parent process at the CDO prompt to the Jim Smith
      process at the system prompt. The process name is entered in
      lowercase characters, which requires double quotation marks.

    3.CDO> SPAWN
      $ SHOW DEFAULT
        USER1:[SMITH]
      $ ATTACH Smith
      CDO> SHOW DEFAULT
        USER1:[SMITH.REP]
      CDO> ATTACH Smith_1
      $SHOW DEFAULT
      %DCL-S-RETURNED, control returned to process SMITH_1

      In this example, the SPAWN command creates a subprocess, and
      the ATTACH commands pass control back and forth between the
      spawned subprocess and the parent process.

    4.CDO> SPAWN RUN SYS$SYSTEM:SQL$
      SQL>
      SQL> COMMIT
      SQL> $ATTACH SMITH
      CDO>
      CDO> ATTACH SMITH_2
      %DCL-S-RETURNED, control returned to process SMITH_2
      SQL>

      In this example, the SPAWN command creates a subprocess to
      invoke SQL and a secondary subprocess that runs SQL. When
      you are in CDO and want to reattach to your SQL subprocess,
      you can avoid subprocess quotas by attaching to the secondary
      subprocess.
