1.2.0 Release Notes

This version was released on 26 October 2003.

New Features

Over 30 new API calls (see below)

Support for Microsoft Visual Basic

Available as both a DLL or static library

The 256-character restriction for Elzed strings has been eliminated for both simple string variables and arrays of strings. Strings created within Elzed may now be up to 32000 characters long. Strings linked into Elzed may be of any length.

Improved support for scientific notation in bases other than 10

Added a "default" case option to select statements

Added a "last result" operator

Parameter names in linked external (callback) operator definitions are now optional. They are still required in expression-based external operator definitions.

Linked external (callback) operators may be defined to take variable numbers of parameters of varying types. While this is not quite the same as operator overloading, it gives you much more flexibility in defining your callback operators.

All API functions and linked external operators now use the __stdcall calling convention

Bug Fixes

Fixed a bug which allowed changes to the "allow implied multiplication" flag to be ignored

Corrected the parameter list order in lzDefineError

Fixed a bug in lzSetStrVar & lzGetStrVarValue which incorrectly recorded and reported the string value

Fixed a bug in lzDeleteOp which incorrectly returned a boolean result code instead of the expected Elzed error code
