Create CharacterToUnicodeMap object from EBCDIC codepage (CharacterToUnicodeMap class)

[Introduced in Sirius Mods 8.0]


This method lets you dynamically select a particular codepage for specific data without having to change your system-wide codepage.

Syntax

%characterToUnicodeMap = [%(CharacterToUnicodeMap):]NewFromEbcdicCodepage[( [codepageName])]

Syntax terms

%outCharacterToUnicodeMap A CharacterToUnicodeMap object.
%(CharacterToUnicodeMap) The optional class name in parentheses denotes a virtual constructor. See "Usage notes", below, for more information about invoking a virtual constructor.
codepageName A string that identifies one of the currently supported codepages at your site. You can view (and manage) these codepages with the UNICODE command.

Usage notes

  • NewFromEbcdicCodepage is a virtual constructor and as such can be called with no method object, with an explicit class name, or with an object variable, even if that object is null:

    %charToUmap = newFromEbcdicCodepage('0037EXT') %charToUmap = %(CharacterToUnicodeMap):newFromEbcdicCodepage('0037EXT') %charToUmap = %charToUmap:newFromEbcdicCodepage('0037EXT')

Examples

The following code sequence shows the use of a Sirius Mods extended codepage, which maps the EBCDIC X'20' character (normally not translatable to Unicode) to the Unicode character U+20AC (the Euro sign):

%tr is object characterToUnicodeMap %tr = newFromEbcdicCodepage('0285EXT') %u = ('20':x):characterToUnicode(%tr) Printtext {~} is {%u:UnicodeToUtf16:StringToHex}

The result is: %u2:UnicodeToUtf16:StringToHex is 20AC
