<Record> is a keyword used to describe variables - structures. The syntax for declaring a variable of type <Record> is:

RecVarName: Record

  RecFieldName1: Type1

  RecFieldName2: Type2

  .....

  RecFieldNameN: TypeN

End

Where

RecVarName – name of varriable;
RecFieldName1...RecFieldNamen – variable field names;
TypeX – record field type. It can be any simple type, record or static array of the above types.

Example:

Rec1, Rec2: record
  X, Y, Z: real
  P: array [3,3] of integer;
  S1, S2: string
end

RR: array [10] of record
  X, Y, Z: real
end

Rec11: record
  field1: integer
  field2: array 10 of string
  field3: record
    nestedField1: real
    nestedField2: array 5 of integer
  end
end

Using Records

Record fields are accessed by using the access operator: "."

In order to assign a value to the record field, you need to use the following expression:

<RecordName>.<FieldName1>{.<NestedFieldName2>...} = x

Example:

Rec1.X = 1; Rec1.Y=2
Rec1.P[1,1] = 0
Rec1.S1 = "W100"

for i=1 to 10 do begin
   RR[i].X = i
   RR[i].Y = 0
   RR[i].Z = 50
end

rec3.field3.nestedField2[1]=33

You can use the value stored in the field as follows:

x = <RecordName>.<FieldName1>{.<NestedFieldName2>...}

Example:

x1=Rec1.X; y1=Rec1.Y

z2=RR[2].Z
