Conditional expressions may differ from the same code in assignment expressions (due to left side exception).

Example:

a as longword

b as byte

if b*5 then... ‘ byte level - general rule will not give same result as

a = b * 5     ‘ word level - general rule + left side exception

if a then...

if b*5 exceeds byte range.

Any expression can be evaluated at specific level by using explicit typecasting. Having in mind previous example, in 

order to get same calculation in conditional and assignment expression, the following should be done:

if word(b*5) then... ‘ word level 

Statements define  algorithmic  actions within  a program. Each statement needs  to be terminated  with a semicolon 

(;). In the absence of specific jump and selection statements, statements are executed sequentially in the order of 

appearance in the source code.

The most simple statements are assignments, procedure calls and jump statements. These can be combined to form 

loops, branches and other structured statements.
