I try to add Forth language to Blockly but having some problems.
How to change the connection of the block using ContextMenu?
How to disable the connection of the Procedure/Control block of the tail?
To provide Blockly.Block.prototype.appendTail() function might be able to solve my problem.
Sincerely

Neil Fraser

More details please?

How to disable the connection of the Procedure/Control block of the tail?

Your purple blocks appear to have the following two lines in them:
this.appendInput('', Blockly.NEXT_STATEMENT, '...');
this.appendInput(';', Blockly.INPUT_VALUE, '...', null);
Just delete the second appendInput line (the one with the INPUT_VALUE) and that connection will disappear.

You might find this page of help:

Sorry,My graph is not correct.
I need label ';' but disable the connection of the Procedure/Control block of the tail.

Interesting. Currently that's not possible. However I'm currently rewriting the renderer to handle some other cases, so I'll also upgrade it so that you can specify 'null' in place of 'Blockly.VALUE_INPUT' and it will not add the notch.

I'm currently preparing for a conference presentation, so this might not land until later in the week. But you can count on it getting done.

I solve my problem.
My solution--> http://jimmyscratchlab.blogspot.tw/2012/06/try-google-blockly-forth.html
Can I call it free style Forth-Lang block?

Done (r287). You can now add the following:
this.appendInput(';', Blockly.DUMMY_INPUT, '', null);

Thanks.
I check out the latest project source code but I can not define a new procedure.

Blockly.Language.procedures_defreturn_1 = {
// Define a procedure with a return value.
category: null, // Procedures are handled specially.
helpUrl: Blockly.LANG_PROCEDURES_DEFRETURN_HELPURL,
init: function() {
    this.setColour(290);
    this.appendTitle(':');
    var name = Blockly.Procedures.findLegalName(Blockly.LANG_PROCEDURES_DEFRETURN_PROCEDURE, this);
    this.appendTitle(new Blockly.FieldTextInput(name, Blockly.Procedures.rename), 'NAME');
    this.appendInput('', Blockly.NEXT_STATEMENT, 'STACK');
    //this.appendInput(Blockly.LANG_PROCEDURES_DEFRETURN_RETURN, Blockly.INPUT_VALUE, 'RETURN', null);

this.appendInput(';', Blockly.DUMMY_INPUT, '', null);

    //this.setMutator(new Blockly.Mutator(this, ['procedures_mutatorparam']));
    this.setTooltip(Blockly.LANG_PROCEDURES_DEFRETURN_TOOLTIP_1);
},
destroy: Blockly.Language.procedures_defnoreturn_1.destroy,
getProcedureDef: function() {
    // Return the name of the defined procedure
    // and that it does not have a return value.
    return [this.getTitleText('NAME'), true];
}
};

Your code is correct. Attached is a screenshot of the resulting block.

This is the issue. Procedures are indeed handled specially. If you
really need to create another type of procedure, you'll need to also
edit Blockly.Procedures.flyoutCategory (in procedures.js).
