NAME
       source - Evaluate a file or resource as a Tcl script

SYNOPSIS
       source fileName

       source -encoding encodingName fileName                                                                |

DESCRIPTION
       This  command  takes  the  contents of the specified file or resource and passes it to the Tcl inter-preter interpreter
       preter as a text script.  The return value from source is the return value of the last  command  exe-cuted executed
       cuted  in  the  script.   If an error occurs in evaluating the contents of the script then the source
       command will return that error.  If a return command is invoked  from  within  the  script  then  the
       remainder  of  the  file  will be skipped and the source command will return normally with the result
       from the return command.

       The end-of-file character for files is "\32" (^Z) for all platforms.  The source  command  will  read
       files  up to this character.  This restriction does not exist for the read or gets commands, allowing
       for files containing code and data segments (scripted documents).  If you require a "^Z" in code  for
       string comparison, you can use "\032" or "\u001a", which will be safely substituted by the Tcl inter-preter interpreter
       preter into "^Z".

       The -encoding option is used to specify the encoding of  the  data  stored  in  fileName.   When  the |
       -encoding option is omitted, the system encoding is assumed.

EXAMPLE
       Run the script in the file foo.tcl and then the script in the file bar.tcl:
              source foo.tcl
              source bar.tcl
       Alternatively:
              foreach scriptFile {foo.tcl bar.tcl} {
                 source $scriptFile
              }
