If I place a rem statement after a command, do I need a colon to separate them?

example


I noticed the book has this all the time.

yes you do need the colon, otherwise DBC views it all as one command and calls a syntax error

A colon will let you stack multiple commands on one line:



And while we are here, is there a way put a command on the same line as the rem after the rem?



I'm not sure if the above code works or not...

look at this

it shows 3 things
1.can put a "if endif" on 1 line

2.if you put a : after a "if then", it will do both commands
ONLY if the statement is true

3.the "print "bob2" does'nt work.

If at first you don't succeed-Pause-Go to last checkpoint

Just think of a colon as the start of a new line.
You can also put multiple statements after an IF
if mouseclick()=1 then print "You clicked the mouse!" : wait 1000
The program will only wait for a second if the mouse is clicked; the wait is part of the if statement. That's one of colon's peculiarities that can be quite useful.
DB makes it a bit confusing by using it to define labels too

There is an eight letter word. You can insert a letter into it or remove a letter from it without changing its meaning. Answer

right I dont understand why they did that

and no once you have declared a rem in a line to my knowledge you cant go back to code in that line after it

Smartguy is right, it treats everything after the rem as remarks

Damn line limits!

I think DBC stores each line as one string, so that limits it to 255 characters.
I don't know how DBP does it.
