'''Locomotive Basic''' is a proprietary dialect of the [[BASIC programming language]] written by [[Locomotive Software]].

It was modified (many custom features to support the platform) for use on the [[Amstrad CPC]] as "Amstrad BASIC" (where it was built-in on [[Read-only memory|ROM]]).

Later [[Locomotive BASIC-2]] was produced for the IBM PC compatibles platform as a GEM application on the Amstrad [[PC1512]] and 1640 and was a descendant of [[Mallard BASIC]],<ref name="theregister smith 20140212">{{cite news | url=https://www.theregister.co.uk/2014/02/12/archaeologic_amstrad_cpc_464/ | title=You're NOT fired: The story of Amstrad's amazing CPC 464 | work=[[The Register]] | date=12 February 2014 | access-date=17 February 2014 | author=Smith, Tony}}</ref><!-- nb="Their Mallard Basic, named because of its speed, had been finished and was undergoing final bug-testing when Perry [of Amstrad] came to call." --> the [[BASIC interpreter|interpreter]] for [[CP/M]] supplied with the [[Amstrad PCW]].

There are two versions of Amstrad; BASIC 1.0 which only came with the CPC464 (and had a buggy <code>DEC$</code> function), and BASIC 1.1 which corrected this and shipped with all other CPCs. BASIC 1.1 was also included in the [[Amstrad CPC#The plus range|Amstrad CPC Plus]] series machines, as part of the included game cartridge.
