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.
This type of character string is in ANSI format.
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 ("").

Fixed string

The memory required by a fixed-length string is allocated when the string is declared. Therefore, you should avoid using very large strings.
Fixed-length strings are filled with spaces. Initializing and assigning a large string (several hundreds kilobytes) may take a long time.

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"
