Translate to Ebcdic (Unicode class)


UnicodeToEbcdic converts a Unicode string to EBCDIC. Optionally, untranslatable characters can be represented with XML style hexadecimal character references.

Syntax

%string = unicode:UnicodeToEbcdic[( [CharacterEncode= boolean])] Throws CharacterTranslationException

Syntax terms

%string A string variable to receive the method object string translated to EBCDIC.
unicode A Unicode string.
CharacterEncode The optional (Name-Required) CharacterEncode argument is a Boolean:
  • If its value is False, the default, an exception is thrown if the input contains any Unicode character not translatable to EBCDIC.
  • If its value is True, any Unicode character not translatable to EBCDIC is replaced with the hexadecimal character reference of the character, and the ampersand character is replaced with &amp;. For example, the eight characters &#x201C; replace the Unicode "left double-quotation mark."

Exceptions

This function can throw the following exception:

CharacterTranslationException
If the method encounters a translation problem, properties of the exception object may indicate the location and type of problem. See CharacterTranslationException exception class.

Usage notes

  • Unless the CharacterEncode argument is used, or you want to Catch a CharacterTranslationException, this function is generally not needed, because a Unicode string is implicitly converted to EBCDIC when used in an EBCDIC context. See the example in "Examples," below.
  • The EbcdicToUnicode method converts an EBCDIC string to Unicode.
  • The UnicodeToEbcdic function is available as of version 7.3 of the Sirius Mods.

Examples

The following example shows multiple calls of UnicodeToEbcdic. The U constant function is used in the example.

%u Unicode Initial('&#x31;':U) Print %u:UnicodeToEbcdic %u = '1&#x80;2':U Print %u:UnicodeToEbcdic(CharacterEncode=True) Print %u:UnicodeToEbcdic

The result of the above fragment is:

1 1&#x0080;2 CANCELLING REQUEST: MSIR.0751: Class STRING, function UNICODETOEBCDIC: CHARACTER TRANSLATIONEXCEPTION exception: Unicode character U+0080 without valid translation to EBCDIC at byte position 5 ...

Note: Because of the implicit conversion of Unicode strings (in this case to String),
the Print %u:UnicodeToEbcdic statements in the example above could be
replaced by Print %u statements and the results would be the same.
