There are tons of influences from ObjectPascal: * Range-based subtyping: You can declare a type as being an int of 1..5. Many Pascal-derived languages (Modula, Oberon, Ada) have this. * Ranges are first-class values and can be used in loops and case statements: "for i in 0..10". * Arrays: "array[1..5] of integer" becomes "array[1..5, int]". Nim also has open arrays, just like ObjectPascal. * Enums. Almost exactly like Pascal. * Sets, eg. "set[char]", which can then assign things like {"a".."z"}, almost exactly like Pascal. * Functions like ord() and prec(). * For a long time Nim used Borland-influenced naming conventions (mainly three: TFoo for classes, PFoo for pointers to objects, FFoo for fields). Fortunately this has been deprecated. * "var", "type" etc. being block-oriented and used to declare multiple things on separate lines. * Functions/methods are called "procedures". (The Nim manual insists this is more correct. I'm not so sure.) * Case insensitive identifiers.
