source - Evaluate a file or resource as a Tcl script
source fileName
source -rsrc resourceName ?fileName?
source -rsrcid resourceId ?fileName?
This command takes the contents of the specified file or resource
and passes it to the Tcl interpreter as a text script. The return
value from source is the return value of the last command
executed 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
interpreter into ``^Z''.
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
}
file, cd, info
file, script
