  Goto (command) - Wikipedia, the free encyclopedia
GOTO is a command found in many programming languages which instructs the computer to jump to another point in the computer program, specified by a label or line number.
However, others believed that even though the use of GOTO is often bad practice, there are some tasks that cannot be straightforwardly accomplished in many programming languages without the use of GOTO statements, such as breaking out of nested loops and exception handling.
Computed GOTO is often avoided even by programmers who use GOTO, since it makes code even more difficult to read: to determine even the possible destinations of the jump requires evaluating the arithmetic expression that controls it.

 Caché ObjectScript Language Reference - GOTO   (Site not responding. Last check: 2007-11-07)
GOTO without an argument resumes normal program execution after Caché encounters a BREAK command in the currently executing code.
If the postconditional expression is appended to the GOTO command keyword, Caché executes the GOTO command if the postconditional expression is true (evaluates to a non-zero numeric value).
If you use GOTO to break out of a FOR, IF, DO WHILE, or WHILE loop, you can go to a tag outside of all code blocks, a tag within the current code block, or go from a nested code block to a tag in the code block that encloses it.

GOTO is a command found in many programming languages which instructs the computer to jump to another point in the computer program.
GOTO is found in FORTRAN, Algol, COBOL, SNOBOL, BASIC, Common Lisp, C, C++, Pascal, Perl and many other languages, particularly assembly languages.
However, others believed that even though the use of GOTO is often bad practice, there are some tasks that cannot be straightforwardly accomplished in many programming languages without the use of GOTO statements, such as exception handling.

 Batch File Command Reference for Windows 2000   (Site not responding. Last check: 2007-11-07)
If command extensions are enabled (the default in Windows 2000), the endlocal command restores the enabled/disabled state of command extensions to what it was before the matching setlocal command was executed.
The for command replaces %%variable (or %variable) with each text string in the specified set until the command (specified in the command-parameters) processes all of the files.
When command extensions are enabled (the default setting in Windows 2000), the shift command supports the /n switch, which tells the command to start shifting at the nth argument, where n can be a value from zero to eight.

 Help: GOTO
After a GOTO command in a batch file, the next line to be executed will be the one immediately after the label.
The colon is required on the line where the label is defined, but is not required in the GOTO command itself.
GOTO begins its search for the label on the line of the batch file immediately after the GOTO command.

 OpenVMS User's Manual
Command lines in a subroutine execute only when the subroutine is called with the CALL command.
Note that when you test the termination variable at the end of the loop, the commands in the body of the loop are executed at least once, regardless of the value in the termination variable.
A command sequence is executed conditionally depending on the execution result of the preceding command sequence.

When the echo command is enabled, subsequent batch file commands are displayed on the screen as they are executed.
Using the shift command, each parameter is shifted one position to the left, so that parameter %1 becomes %0, parameter %2 becomes %1 and so on.
Each shift command causes all parameters to be shifted to the left by one position.

 Batch Guide
command moves everything down by one allowing parameters past the ninth to be retrieved (this wipes out the %0 parameter so if used for the batch to call itself it must be saved to another variable).
The first line turns off command echo (contained at the beginning of almost all batch files), the next line ensures the C drive is active, then it changes to the correct directory using the cd command and runs the game with the correct command line parameter.
The command line is stored in the variable %parm%, if the first parameter %1 is empty, %parm% is set to a useful default, for SCAN this translates to "scan the current and all subdirectories under it, do not scan memory".

 Shell Scripting 101, Lesson 9
In the Goto command’s syntax, you might have noted that the colon is in square brackets.
If you use the Call command to jump to and execute a subroutine, the command interpreter assumes that the subroutine ends at the end of the file (i.e., with the last command in the script).
If the file is on the D drive, the command interpreter jumps to the :Delthemd label, deletes the file, and jumps to the end of the script.

 Microsoft Windows XP - Goto
When the label is found, it processes the commands that begin on the next line.
If command extensions are enabled (that is, the default) and you use the goto command with a target label of :EOF, you transfer control to the end of the current batch script file and exit the batch script file without defining a label.
When you use goto with the :EOF label, you must insert a colon before the label.

Many DOS commands provide exit status values to indicate whether they were successfully executed, and if they weren’t the cause of the error.
If the exit-status is less than the specified value, DOS continues processing with the next command in the batch file.
The goto command gives you the ability to direct which set of commands are executed, and which set of commands are skiped within your batch file.

A GOTO command is used to change the flow of execution to a label in the procedure.
The EXIT command is not required at the end of procedures because the end-of-file of the procedure causes an implicit EXIT command.
This type of command procedure is useful when there is a set of parameters or qualifiers that you use frequently with one or more commands.

 Why Tcl has no GOTO command
Inside that loop you have breaks, which essentially are goto's to the end of the loop.
SS Also note that you don't need break to exit from switch branches (like in C), so one of the uses of goto in C (to exit a while loop that contains switch) is a non-issue in Tcl:
I think that goto's should be used very sparingly, but there are definitely situations where programs are a lot clumsier without them.
