I am converting some old Code and want to try and replicate loading data files using Bytes, Shorts and Strings as the data for various things.

WriteString(levfile,levdesigner$(l))
WriteString(levfile,levcreation$(l))
WriteString(levfile,levlastsave$(l))
WriteByte(levfile,levprotect(l))
WriteString(levfile,levnam$(l))
WriteByte(levfile,levdim(l,0))
WriteByte(levfile,levdim(l,1))
For y=0 To levdim(l,1)-1
    For x=0 To levdim(l,0)-1
        WriteShort(levfile,map(l,x,y))
    Next
Next

levfile is the name of the data file

Above is the old code i used to write the data file, is there anything equivalent in javascript?

So if i store a TEXT file on ther server with this saved structure, can you read it from the file on the server?
