M2000 start as an experimental interpreted language, using a Module in Module idea (like a Procedure in Procedure) where each inner Module is closed for modification, but open for expansion, by replacing code at run time. Code executed in one pass. There is a pre-pass to determine the major type of an expression, a number or a string. Look this paradigm: We call inner Beta in two stages. Ins second stage we change inner Theta with Theta2. This is the decoration of Beta with Theta as Theta2. This is a temporary decoration because Beta after execution erase any new identifier including Theta. So each time we call Beta, statement Module Theta make this module unless a decoration stop it.

Module Theta (x){

Beta ; Theta as Theta2</lang>
==Greek Vocabulary==
<lang >Τμήμα Βήτα {
Τμήμα Θήτα (χ){
Τύπωσε "Αυτό είναι το Θήτα, θα πάρουμε το χ=";χ
}
Για ι=1 έως 3 : Θήτα ι : Επόμενο ι
}
Βήτα
Τμήμα Θήτα2 (χ) {
Τύπωσε "Αυτό είναι το Θήτα2, θα πάρουμε το χ=";χ
}
Βήτα ; Θήτα ως Θήτα2</lang>
