Assignment Statements
Assignment statements have the following form:
variable = expression
The statement evaluates
expression
and assigns its value to
variable
. All the rules of implicit conversion are
applied.
Variable
can be any declared variable or array element, and
expression
can be any expression.
Do not confuse the assignment with relational operator = which tests for equality. mikroBasic PRO for dsPIC30/33 and
PIC24 will interpret the meaning of the character = from the context.
Conditional Statements
Selection or flow-control statements select one of alternative courses of action by testing certain values. There are two
types of selection statements:
- if
- select case
If Statement
Use the keyword
if
to implement a conditional statement. The syntax of the
if
statement has the following form:
if expression then
statements
[else
other statements]
end if
When
expression
evaluates to true,
statements
execute. If expression is false,
other statements
execute.
The
expression
must convert to a boolean type; otherwise, the condition is ill-formed. The
else
keyword with an
alternate block of statements (
other statements
) is optional.
Nested if statements
Nested if statements require additional attention. A general rule is that the nested conditionals are parsed starting from
the innermost conditional, with each
else
bound to the nearest available if on its left:
if expression1 then
if expression2 then
statement1
else
statement2
end if
end if
