|s1 s2| s1 := 'abcdefghijk'. s2 := String streamContents: [:s | s1 keysAndValuesDo: [:index :each | (index \\ 3 = 1 and: [1 < index]) ifTrue: [s space]. s nextPut: each]]. is perhaps a little simpler. I generally prefer to have Smalltalk do the counting for me. On Tue, 28 Apr 2020 at 07:25, Todd Blanchard via Pharo-users <pharo-users@lists.pharo.org> wrote:

Hello,

I wonder if it is possible in Pharo to divide a string in lets say part of 3. so this : 'abcdefgh'

would be 'abc def gh`

Do you really want a single string with spaces inserted or do you want a collection of substrings, each three characters (or less, for the last one)?

I need a single string with spaces inserted. So maybe I have formulate my question wrong. Very difficult if English is not your mother language and you were bad at school in languages a very very long ago.
