Re: Smalltalk String Length Code?

Find out.

*starts Lion*
*opens the browser*
*goes to Scratch-Objects > ScriptableScratchMorph > class > blockSpecs*
*finds the length block*
*goes to Scratch-Objects > ScriptableScratchMorph > string ops > stringLength:*
*finds this code:*

stringLength: t1
    t1 isUnicode ifTrue: [^ t1 asUTF32 size].
    ^ t1 asString asUTF32 size

Re: Smalltalk String Length Code?

The length command is size.

Code:

'hello world' size

This code returns 11.
