Greetings.  I found a useful method.  Only thing is
I don't know how to write the character code for no character.

'12%31%%1232' replaceAll: $% with: $.   '12.31..1232'

'12%31%%1232' replaceAll: $% with: $* '12*31**1232'

'12%31%%1232' replaceAll: $% with: ''  ==> error
'12%31%%1232' replaceAll: $% with: Nil  ==> error


I looked for a deleteAll: method but there is none for Strings.



Thank you for your help.

Joe.
