Commands in GWBASIC

Question

I am using GWBASIC and cannot figure out a few things. Like, when I'm saving a program after running it with F4, it says: File not found.

Secondly, when I'm using auto command it shows * with line numbers.

Finally, if I want to take program and its output's print on paper, what should I do?

I am using GWBASIC and cannot figure out a few things. Like, when I'm saving a program after running it with F4, it says: File not found.

Try saving like this:

SAVE"myprog.bas",a

Secondly, when I'm using auto command it shows * with line numbers.

The star (*) on a line means that line already exists and you are overwriting it. If you use the command NEW to wipe-out the program from memory before running 'auto', you won't see those stars on lines.

Finally, if I want to take program and its output's print on paper, what should I do?

1) Save the program as a text file:

SAVE"myprog.bas",a

2) Open the file 'myprog.bas' with a text editor (like Notepad++).

3) Print it.

Answer 2

To print a GW-BASIC program, use the LIST command.

The optional , filename parameter specifies the output for the listing. It could be to a file (e.g. to dump the text so another program can load it), or it could be to a printer device (e.g. LPT1:).

So this should work:

LIST ,LPT1:
