I think Scratch should have a Remove block and Replace block for variables and lists.
It would work like this.

Replace block:
[When flag clicked]
[Set (Whatever) to (1222333111222)]
[Replace (1)s of variable (Whatever) with (5)s]

(Now the Variable would look like this: 5222333555222).
------------------------------------------------------------------------------
Remove block:
[When flag clicked]
[Set (Whatever) to (192399994999999999999599996)]
[Remove (9)s of variable (Whatever)]

(Now the Variable would look like this: 123456).
-----------------------------------------------------------------------------
These blocks would be EXTREMELY helpful to me.
And I would love it even more if you could remove/replace, Spaces.

Well, that would be nice, but hard to code.

Well, every block in scratch is coded in Squeak.

For example, the move (num) steps block's codde looks like this:

Code:

forward: t1 
    | t2 t3 t4 t5 t6 |
    t2 _ rotationDegrees degreesToRadians.
    t3 _ t2 cos @ t2 sin * t1.
    t4 _ self position + t3.
    t5 _ t4 x.
    t6 _ t4 y.
    t5 isNaN ifTrue: [t5 _ 0].
    t5 isInf ifTrue: [t5 _ t5 sign * 10000].
    t6 isNaN ifTrue: [t6 _ 0].
    t6 isInf ifTrue: [t6 _ t6 sign * 10000].
    self position: t5 @ t6.
    self keepOnScreen

So something even less simple would require more code.

Oh, I thought you were talking about something else.

My ROT13 project's script would be so much shorter if I had that tongue

So you support? tongue

I support this idea.

It should be a single reporter block: (replace [] with [] in []). To remove, leave the WITH field blank. wink
And Scratch 2.0 is going to be in Flash, and I think they have a function that does exactly this. big_smile

GREAT! big_smile
I'm working on a project where this feature is Vital.

Yeah. But maybe they'll have it scratch 2.0
