We will continue to support Visual Studio 10 until ESL release 20.10 and will then switch to Visual Studio 2017.

 

Release 18.10

13th April 2018 This release introduces ESL Inter-Process Communication (Esl IPC) which allows ESL programs to communciate with C# or VB.net programs giving simple but robust access to Microsoft Office projects.

We have included a couple of samples to get you started. The release also includes enhancements and bug fixes for Layout Editor, EslEdit and other programs.

 

Release 17.20

Release 17.10

16th June 2017

 

Release 16.20

Release 15.20

30th November 2015 EslEdit has been enhanced and helps developers to write ESL programs even more quickly. Additionally, a new remote communication library "socket" has been added.

This can be used instead of "serial", which removes the need for additional hardware or a third-party virtual serial port package.

 

Release 15.10

30th June 2015

 

Release 14.20

12th November 2014 We have added some more tracing/logging options and have revised the calling conventions to optimise the support for COBOL libraries.

 

Release 14.10

4th June 2014

 

Release 13.20

2nd October 2013

 

Release 13.10

15th April 2013 As Microsoft is dropping support for Visual Studio 6 (VS6) we have introduced a version of ESL built using VS10 and by default we will supply the version built using this.

If your ESL Application uses any of your own dynamic link libraries (.dlls) that access any ESL functions in ESLLIB, then these libraries must be re-linked to ensure that the correct calling conventions are used.

We will continue to support ESL built using VS6 as long as we have a demand for it and both versions will be kept in step wherever possible.

Where there are platform differences, such as later versions of system calls, we will use the newer versions in VS10 and the older version in VS6.

 

Release 12.20

25th October 2012 This release has been tested against a pre-release version of Windows 8.

If you intend to use the full-screen mode offered by ESL then you will appreciate that this is also the first release of ESL that fully supports “Popup Menus”.

This is significant as the dropdown menus are unavailable when using full-screen mode.

 

Release 12.10

26th June 2012 In addition to a number of fixes and improvements, we've added some documentation in the release notes for OSUTIL under the "General Information" section and we now have an ESL language Quick Reference Guide.

 

Release 11.20

11th October 2011 We've made a number of significant improvements to Esl Edit.

We'd like to think that this would be your preferred development tool for ESL programs so please do let us know if you think it is missing functionality in any way.

 

Release 11.10

22nd June 2011

 

Release 10.20

2nd February 2011 The simple text editor that was previous released has been considerably enhanced to create a multi-window development environment.

This new tool, Esl Edit parses your source code, providing direct access to:

oAction routines

oSubroutines

oIncluded files and

oFunctions

Esl Edit also parses error logs, and locate the reported error by loading the associated application source code.

Together with the enhanced editing facilities, the Programmer can invoke the common Esl Development tools:

oCompiler

oLayout Editor

oQuikStep Debugger and

oThe Esl Runtime

Esl Edit has been written in the Esl Language using only the libraries and modules that are available to all Developers. We encourage you to contact the Help Desk, to suggest possible enhancements and to obtain the latest pre-release versions of ESL Edit to trial.

3rd December 2007 This release contains functionally equivalent to 7.02 but in addition to the version built using Visual Studio 6 is now available as a version built using Visual Studio 8.
