If some method is not just a thing hanging around waiting for nothing (no senders, for example), you always will find its full implementation+use - that's the nature of the Smalltalk/Squeak system.
senders of #translateFrom:to:table: =>String>>#translateWith:
senders of #translateWith: (nice examples for what the table argument is about) =>String>>#translateToLowercase =>String>>#translateToUppercase
implementors of #translateFrom:to:table: =>ByteString class>>#translateFrom:to:table: =>ByteSymbol class>>#translateFrom:to:table: =>String class>>#translateFrom:to:table:
The String implementation tell exactly what argument is used for what, same with the primitive fallback code of the ByteString implementation.
Hope that helps.

That works for lots of methods. But for some methods there are no decent comments or examples. This is what I get from "Senders of translateFrom:to:table:" translateWith: table "translate the characters in the string by the given table, in place" ^ self translateFrom: 1 to: self size table: table
I don't find see anything called "references". I cannot find a single example of what a table arguments should look like.
Here's a simple example of what I want to do:
myString := 'ACGTACGT'. myFixedString := myString translateFrom: 1 to; (myString size) table: table.
Where table would be something like a hash: A => 5, G => 6, C => 7, T => 8.
in Perl, I would write: perl -pe 'tr/AGCT/5678/' <return> on the command line and then paste in the string and perl would return the translated string.
Thanks for your help. Tom Keller

Hi thomas,
You can find some sender of it by right click -> more.. -> senders of
it
And there is a way to avoid stinkin' right-click: in any text, select the text of a selector (including its arguments) and do cmd-m and cmd-n :) For example, in a browser with the class definition template (Object subclass: #NameOfSubclass ...) do select from subclass: to category: and see what I mean.
So you can understand how people use it.
Yes, one of the best ways to come to use to Smalltalk/Squeak.

Other wise find the references to it and you can read comment of the metod or even understand the implementation. (follow same method for 'sender of it' but chose 'references to it')
