The value at a specified position in the input string (Unicode class)


This function returns the string value of the single character at a specified position in the method object Unicode string.

The UnicodeChar function is available as of version 7.5 of the Sirius Mods.

Syntax

%outUnicode = unicode:UnicodeChar( position)

Syntax terms

%outUni A Unicode variable to receive the result of the UnicodeChar method.
unicode A Unicode string.
position 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 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.

Example

The following request calls UnicodeChar two times:

Begin printText {'inaugural':unicodeChar(5)} %u is unicode initial('xyz&#xA1;':U printText {%u:unicodeChar(4)} End

The result is:

g ?

The question mark in the result represents an EBCDIC character that is not displayable.

For further information about the above request, see descriptions of:

  • the PrintText statement
  • the instrinsic String U function
