| − | A data field of the '''LongInt''' data type can only take integer values with and without sign.
| |
| − | Assigning other values leads to compiler error messages when the program is compiled and the compilation process is aborted. That is, the executable program is not created.

| − | Definition of a Longint data field:

| − | <syntaxhighlight lang=pascal>
| |
| − | var
| |
| − | left : Longint;

| − | Examples of assigning valid values:
| |
| − | | |
| − | <syntaxhighlight lang=pascal>
| |
| − | left := -2147483648;
| |
| − | left := 0;
| |
| − | left := 2147483647;

| − | Examples of assigning invalid values:
| |
| − | | |
| − | <syntaxhighlight lang=pascal>
| |
| − | left := '-2147483648';
| |
| − | left := '0';
| |
| − | left := '2147483647';

| − | The difference between the two examples is that the upper example is the assignment of literals of the type integer, while the assignment of the lower example is literals of the type String.
