UnicodeLeft (Unicode function)

The left-most characters of the string (Unicode class)

UnicodeLeft returns the left-most characters of the method object string, possibly padding it on the right.

Syntax

%outUnicode = unicode:UnicodeLeft( number, [Pad= c])

Syntax terms

%outUnicode	A Unicode variable to receive the result of the UnicodeLeft method.
unicode	A Unicode string.
number	The number of the left-most characters to return. If unicode is shorter than the requested number of characters, it is either padded to the requested length or returned with no padding, depending on the value of the Pad parameter.
Pad	A single character used to pad unicode, on the right, if it is shorter than the requested number. c defaults to a null string ('') which means no padding is done. Pad is a Unicode string; like all Unicode arguments, if an EBCDIC string is specified, it is converted to Unicode. Pad is a name required parameter.

Usage notes

• The number value must be a non-negative number. A negative number results in request cancellation.
• The Pad parameter value must be either null or a single character. A longer value results in a compilation error.
• UnicodeLeft is available as of Sirius Mods Version 7.5.

Examples

1. The following statement displays Model 2:

   %u is unicode initial('Model 204™':U) printText {%u:unicodeLeft(7)}

2. The following statement displays Model 204!!!:

   %u is unicode initial('Model 204') printText {%u:unicodeLeft(12, pad='!')}

3. The following statement gets a character translation exception because the Unicode character ™ (trademark) has no EBCDIC equivalent:

   %u is unicode initial('Model 204™':U) printText {%u:unicodeLeft(10)}
