Pascal string of (Variable type)

In french: Chaîne Pascal sur

Warning
This type of variable is kept for backward compatibility.

The Pascal string of type corresponds to a length-prefixed string (this length is stored as a byte value). This byte is not accessible. For example string[1] represents the first character of the string and not its length.

The length of a Pascal string cannot exceed 255 characters. The length given to the Pascal string must be equal to the length of the string.

Remarks:

This type is available for compatibility with other programming languages (e.g., Turbo Pascal for Windows).
The Pascal String type is not supported. It is replaced with the String type.
For a variable of type "Pascal string of", TypeVar returns the wlPascalString constant (value: 21).

Example

FirstName is Pascal string of 8
FirstName = "Florence"

Syntax

Declaring and initializing a "Pascal string of" variable Hide the details

<Variable name> is Pascal string of <Length> = <Value>
OR

<Variable name> is Pascal string of <Length>
<Variable name> = <Value>

<Variable name>:

Name of the variable to declare. When several variables of the same type are declared and initialized on the same line, only the last variable is initialized.

<Length>:

Length set for the string. It must be equal to the length of the string.

<Value>:

Value given to the variable.

Remarks

Default value

A declared and uninitialized "Pascal string of" variable corresponds to an empty string ("").

Cross-platform code

Fixed-length strings are not available in Java. They are replaced with the String type at runtime.

However, Complete can be used on a String variable:

MyString is string
MyString = Complete("Test", 10)
// Equivalent to 
// MyString is fixed string of 10 characters
// MyString = "Test"
