Okay so I'm trying to add line 1 from a txt file to a variable. Then after my script does what it does, it goes to line 2 of the same txt file and adds that to a variable. How would I go about doing this?

to read in the data from your file into the variable, check out the %read() function. You can choose between #FORALL, #LOOP, and #WHILE/#UNTIL for your looping.

Yeah I've read it and still not sure exactly how to get it working. I've tried it, but don't have much luck. Iwould do something like this?

#file 1 something.txt
#var whatever %read(1,1)

But not exactly sure ... it says something about 0 doing the sequential line ... that sounds like what I'd want..

You're going to need to loop it like he said.

But you'd do something like:
#FILE 1 something.txt
#LOOP %filesize(1) {#var whatever %read(1, %i)}

Obviously this is contrived. And just keeps resetting the whatever to each line of the file until file ends.

But I'm not sure where your #var assignment is in relation to the rest of the script. If it is all in an alias like this:

#ALIAS dork {
#var whatever blah
command1
command2
command3
}

Change it to this:

#ALIAS dork {
#LOOP %filesize(1)
#VAR whatever %read(1,%i)
command1
command2
command3
}
}

Or you could use 0, I never noticed that when using %read before. Course I didn't use it much either :)

Actually what I'm trying to do is make it pull it to a variable, intiate an alias, than pull the next line to that same variable replacing whats in it, initiate alias, etc til the file is empty.

So like:

pull to variable
do alias
pull next line to variable
do alias
pull next line to variable
do alias
etc etc etc.

So your way to initiate this could be:

#ALIAS dork {
#LOOP %filesize(1)
#VAR whatever %read(1,%i)
doalias
}
}
