The value at a specified position in the input string (String class)
This intrinsic function returns the string value of the single byte at a specified position in the method object string; it treats the object string as a
character array.
The Char function is available as of version 7.3 of the Sirius Mods.
Syntax
%outString = string:Char( position)
Syntax terms
| %outStr | A string variable to receive the result of the Char method. |
|---|---|
| string | The string to which the method is applied. |
| location | The position in the method object string of the character you want to identify. A value of 1 finds the first character in the string. |
Usage notes
- The position value must be a non-negative, non-zero number; a zero or negative number results in request cancellation.
A length value greater than the declared length of the output string results in request cancellation.
- For a given position, the Char function returns the same value as the Substring function with a length argument of '1'.
Example
The following statement displays the 's' character:
printText {'Conestoga':char(5)}
