Like functions, Procedures are simple instruction statements that are entered into your script by entering its name and providing the appropriate parameters (or arguments) as parameter names or values into a statement block within parentheses between a begin statement and an end statement. 

At the end of the procedure line, following the closing parenthesis, is a semi-colon (;).  This is known as a procedure call.   

The following example calls the procedure LogInfo and passes in a single parameter contained inside the single text quotes within the parentheses ‘This is the text to be written to the log.’);

LogInfo('This is the text to be written to the log.');

When calling a Procedure that has multiple parameters, these parameters are separated by a comma such as in this call below.

The Procedure Delete passes in three parameters - the value in the variable MyStringVariable and the values of 1 and 15.   This is an example of a Procedure that modifies the input parameter MyStringVariable, and starting at position 1, deletes the next 15 characters.  

At the end of this procedure call, MyStringVariable will have had the first 15 characters deleted.

Delete(MyStringVariable,1,15);

Procedures cannot be used on the right-hand side of an assignment operator. This is because a Procedure does not return a result, therefore it cannot be assigned to a variable in the same way as a function can.

You must always pass in a value for each parameter listed within the parentheses - if three parameters are required then you must pass in all three parameters. It is not possible to completely skip or ignore a parameter, however you can pass a blank or null value in some cases.

To call the user-defined Procedure called RemoveNonKeyboardChars, you could use the following to remove the non-keyboard characters that are included in the string called WhatName.

procedure ScriptEvent (var Value : variant);
var
WhatName, WhatName2 : string;
begin
WhatName := 'Line1 x βæ©';
WhatName2 := WhatName;
RemoveNonKeyboardChars(WhatName2);
LogInfo('Non-keyboard string is >>'+WhatName+'<<');
LogInfo('Keyboard string is >>'+WhatName2+'<<');
end;

There are no parameters to include in the call of the procedure DumpDataview, as illustrated below. Remember that the procedure name is not case sensitive.

procedure ScriptEvent (var Value : variant);
begin
......
dumpdataview;
......
end;
