Command of the day

[Rod]

This will be an index page to the Keyword or Command featured as Command of the day. Now it will take longer than a day to discuss and show examples of each key word but you will get the concept. Gaslouk suggested this activity.

What we intend to do is take lesser know keywords or commands and show how they work and what hints tips and traps there are in using more common commands. This page will be the index page and I will up date it as the commands are discussed. Each command will have its own thread. If you start one please title it "Command of the day "+the command name. FILES is our first command. Please join in, this is for fun and intends to get you using commands you may not have used before.


FILES a command to explore your files and folders.
REM a command to add a remark within a program.
TRACE a command to control the program flow in the debugger.
CommandLine$ a system variable that passes info into a program.

Is the OP responsible for setting the link in this topic's first post?

[Rod]

Yeah my bad. But it is bit fragmented now and isn't really focused on "unusual" commands.

What is the relationship between Liberty BASIC and JUST BASIC?

Yesterday, I got the DEP error "a non-continuable protection violation has occurred. Check ERROR.LOG file."  

Your post from Mar 5, 2019 at 11:47pm worked like a champ.  Thanks.

I am puzzled how that item got switched off of default.

What does the relationship between Liberty Basic and Just Basic have to do with Command of the Day?  But to answer the question, JB is a cut-down version of LB.

A non-continuable protection violation normally occurs when a dll or portion of native code attempts to store data where it does not belong.  That can happen in native code when writing storing data in an array outside the array bounds.  Some times the LB error notification gets mixed up.

Walt,
Can you provide a specific example that shows this occurring? I do not recall ever having a non-continuable protection violation error while attempting to access space outside of an array's bounds.

Mr. Parker, I can not at this time. I will have to go through about 200 backups to find it. As I recall, at first it gave me one of those Sr16 errors. Then stepping through the code it stopped at a variable that was not an array and the out of bounds error.
