Overview
Assignments are one of the key building blocks in B4P and most other programming languages where a value is written (i.e. assigned) to a destination variable or a table entry. Only the actual target variable will be updated, regardless if that variable contains further array and/or structure members. All assignments consist of 3 elements:
- A LHS Expression located on the Left-Hand Side of the assignment symbol or assignment operator, followed by
- the assignment symbol = or a valid assignment operator, and concluded by
- a RHS Expression located on the Right-Hand Side.
LHS Expressions specify destination locations in variables and tables, while RHS Expressions return specified, retrieved, or
calculated values.
Examples
echo(Some simple assignments);
a[] = 1;
a[text] = Hello World;
a[bool] = true;
a[today] = date(today);
a[calc] = 3 + 12*5;
see(a[]);Some simple assignments
a[] 1 "1" (numeral,full access)
bool true (boolean,full access)
calc 63 (plain numeral,full access)
text Hello World (softquoted string,full access)
today 2024-10-19 (plain date,full access)
