Chr

FreeBASIC

Chr
 
Returns a string of characters from one or more ASCII integer values

Syntax

Declare Function Chr ( ByVal ch As Integer [, ... ] ) As String

Usage

result = Chr[$]( ch0 [, ch1 ... chN ] )

Parameters

ch
The ASCII integer value of a character.

Return Value

Returns a string containing the character(s).

Description

Chr returns a string containing the character(s) represented by the ASCII values passed to it.

When Chr is used with numerical constants or literals, the result is evaluated at compile-time, so it can be used in variable initializers.

Asc performs the opposite function, returning the ASCII code of a character represented by a string.

Example

Print "the character represented by";
Print " the ASCII code of 97 is: "; Chr(97)

Print Chr(97, 98, 99) ' prints abc

' s initially has the value "abc"
Dim s As String = Chr(97, 98, 99)

Print s


Dialect Differences

  • The string type suffix "$" is obligatory in the -lang qb dialect.
  • The string type suffix "$" is optional in the -lang fblite and -lang fb dialects.

Differences from QB

  • FreeBASIC accepts multiple integer values as arguments, QB accepted only one.
  • FreeBASIC evaluates the CHR function at compile time when used with constants or literals.
