ScriptBasic / ScriptBasic using AJAX
Last post by John Spikowski - Nov 12, 2022, 04:39 PM
This EXAMPLE shows how AJAX can be used with the ScriptBasic application http proxy server. A drop down list control is used to select the product line you wish to be shown and does an AJAX call to populated the grid.

ScriptBasic / ScriptBasic Introduction
Last post by John Spikowski - Nov 05, 2022, 07:05 PM
Script BASIC is written in ANSI C with an object like API. The scripting engine is embeddable, with a thread safe memory manager and virtually unlimited expandability. The core language uses one source tree for all platforms. Variables are maintained in a variant like structure and typeless until used.

Script BASIC comes with an array of industry standard library extension modules and a multi-threaded proxy HTTPD application server running as an OS service.

Scripting doesn't get any easier and based on a language syntax we all grew up with.
