The following syntax examples are incorrect ways to initialize a variable in pascal:
var current: string = '1.6';
Error message: Column 21: Semicolon (;) expected.
var current: string;
current = '1.6';
Error message: Column 1: Duplicate identifier 'current'.
Correct syntax to initialize a variable in Pascal:
var current: string;
begin
current := '1.6';
end

I haven't codified in Pascal for a long time, but the assignation of a variable uses the := operator (assigment operator), = operator is for comparisitions. Otherwise you need to add the main program block, like this:
Var
current: string;
Begin
current := '1.6';
End.
I hope can be useful for you.
