Affectation
To affect a value to a variable, use the
following syntax :
VariableName = expression
|
First, expression is evaluated, then it is affected
to the variable. The only condition is that expression
and variable must have the same type, at least in
size (in bytes) ! Only strings can have different
sizes (but they are always under 50 characters)
In expression, try not to put uneeded parentheses.
For example, for an integer expression, you can
use integer terms or functions that returns an integer.
Otherwise, you'll have a Type Mismatch error.
To affect a value to a string, this is the same thing. To concatenate, use the "&" operator.
Example :
Local str1 as String
Local str2 as String
Local together as String
str1 = "Hello "
str2 = "world !"
together = str1 & str2 |
So the string together contains "Hello world !"
Implicit declarations
When you make an affectation to an undeclared variable,
the compiler will declare it and will return a message
in the debug window.
