The value at a specified position in the input string (Unicode class)
The UnicodeChar function returns the string value of the single character at a specified position in the method object Unicode string.
Syntax
%outUnicode = unicode:UnicodeChar( position)
Syntax terms
%outUnicode | A Unicode variable to receive the result of the UnicodeChar method. |
---|---|
unicode | A Unicode string. |
position | The position in the method object string, unicode, 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 value greater than the declared length of the output string results in request cancellation.
- For a given position, the UnicodeChar function returns the same value as the UnicodeSubstring function with a length argument of
1
. - The UnicodeChar method is analogous to the intrinsic String Char function.
- UnicodeChar is available as of "Sirius Mods" Version 7.5.
Example
- The following request calls UnicodeChar two times:
begin printText {'inaugural':unicodeChar(5)} %u is unicode initial('xyz¡':U printText {%u:unicodeChar(4)} end
The result is:
g ?
The question mark in the result represents an EBCDIC character that is not displayable.
