TSE: Parser: Syntax: Structure: Serial: Occurrence: &: And: How create 
parser for serial occurrence?

---

e.g. Suppose you define that after an '=' sign it must be followed by 
a value.

---
---

In words:

An assignment contains an equal sign, which must be followed by a 
value.

---
---

In Backus Naur Form:

 [value]

---
---

In Backus Naur Form diagram:


 -->--[value]-->--


---
---

In pseudo code:

if not 'value'
 return 'error'
else
 get 'value'
endif

---
---

As a regular expression:

---


use concatenation.

---

if one character, just the character

 v

---

as a group of characters:

 {value}
