# Testing BlocklyToSmartPascal

This section contains some of our tests of BlocklyToSmartPascal. You can use the tests as further examples from which to learn. Our demonstrations also form part of our testing, so we include them in our links to examples of the use of each type of block. The blocks are arranged below in the order that they appear in the toolbox.

Our initial aim was to provide at least one working example of each type of block, preferably covering all of the options. You may find that a block needs to operate on a variable rather than on a hard-coded string or number (or vice versa). For example, in Smart Pascal, the instruction `([3,2,4]).sort;` causes the error message 'Syntax Error: Array method "sort" is restricted to dynamic arrays'. It is then up to you to develop a workaround. (We sometimes resort to little workarounds with new commercial software).

Sometimes the generated Smart Pascal code contains unnecessary pairs of parentheses. One of these pairs may be necessary in more complex situations, so we generate them both to be on the safe side. If you see an expression within two matched pairs of parentheses e.g. `intOneEqTwo := if Boolean((1 = 2)) then 10 else -10;`, you can safely remove one of the pairs.
