1  ATTACH
   PCA Command

   Passes control of your terminal from your current process to
   another process.

   Format

     ATTACH  process-name
 

2  Parameters
 

process-name

   Specifies an existing process to which you want to attach the
   terminal. If the process name includes spaces, enclose the name
   in quotation marks.
 

2  Description
   The ATTACH command allows you to connect your terminal to another
   process. Using the ATTACH command, you can switch control back
   and forth between several different active processes. To create
   additional processes, use the SPAWN command from within PCA or at
   DCL level.
 

2  Examples

 PCAC> SPAWN            ! Spawn subprocess NICK_1
 $ TYPE FOO.DAT         ! Enter DCL commands in subprocess
 text line in foo.dat
 $ ATTACH NICK          ! Attach to original process
 %PCA-I-RETURNED, control returned to process NICK
 PCAC> SHOW LANGUAGE    ! Enter Collector commands
 Language: PASCAL
 PCAC> ATTACH NICK_1    ! Attach back to subprocess
 %PCA-I-ATTACHED, terminal now attached to process NICK_1
 $

     In this example, a subprocess is created with the Collector
     SPAWN command. DCL commands are executed in the subprocess.
     An ATTACH command at DCL level reattaches the terminal to
     the Collector session. The Collector session continues with
     additional Collector commands until a Collector ATTACH command
     is entered. This ATTACH command connects the terminal to the
     subprocess again so that more DCL commands can be entered.
