Customising Your QL

Here’s a very interesting, little known fact about JS and MG ROM QLs (and all Thors too). Included in JS/MG the ROM of a machine is a new keyword called TRA. Now, some people originally thought that this was a long sort after Trace facility. Not so! It’s even more fun than a boring old trace command. What it enables you to do is to customise our QL! Yup, using the TRA command we can set up a new table in memory to hold the text definitions for the error commands.
