So, a couple of things.
First of all, thanks for unlocking so people can help.
I'm not sure what the title is supposed to mean. A bottomprint that random numbers? There should be a verb somewhere in there, otherwise that sentence makes no sense.
"how you" should probably be "how do you"
"that is repeats" should probably be "that repeats"
"and random numbers" makes no sense.
If you aren't sure how to construct your sentences to express your request, you will probably have a very hard time coding.
If you want to display bottomprint, the correct code is:
commandToClient(%client, 'bottomprint', "String goes here", #);
Also, that is not how a string is used. A regular string includes the text that you put in quotes " ", which you can combine with other strings with commands such as SPC (space), @ (and), TAB (tab, which is kinda like 5 spaces), or NL (next line).
All variables (things that start with a % or a $) can be treated as strings. Some examples of combining strings are below:%random = getRandom(0, 50); //gets a random number between 0 and 50, thought you might like to know
%str1 = "hello there!";
%str2 = "Nexus";
$string = %str1 SPC "my name is" SPC %str2;
$string is now "hello there! my name is Nexus"
Please note that you do not put the variables inside of the quotes, because that will display the name of the variable, not the text saved in the variable.
also you do not put a ; after the arguments of a function.
