When you boot, you can select an acct to login to, unless you compile OSMain soas to pick one. Your acct directory is your HOME directory and all your user data should be placed in here to ease backing-up your data. When you Install an application it will create a subdirectory of your HOME directory for storage. /LT/Apps Applications are placed in subdirectories of /LT/Apps. Applications should have a file called Install.CPZ which will install the app for the current user acct. The file, Load.CPZ will load the application into mem. The file, Run.CPZ, will usually load and execute the app. To add an app to your personal menu, use <CTRL-L>, insert a macro with the PopUp option checked and invoke the Run.CPZ file. /LT/Demo Here you can find lots of sample code to do various things. /LT/Doc Here you can find documentation. /LT/OSMain The core of the operating system is found here. Since priviledge levels are not used, calling it a "kernel" would be confusing, but that's what it is. It is statically compiled by InstallBoot(). It is loaded by the boot loader and must fit in 640K. /LT/Compiler The compiler module src code is found here. The compiler is statically compiled to produce a binary file which is loaded at boot. It is also statically compiled by InstallBoot(). /LT/Adam The non-kernel part of the operating system is found here. It is JIT compiled during boot. -] DOLLAR SIGN CMDS Dollar Sign Cmds are rich-text cmds. The editor, compiler, assembler and operating system are seamlessly equiped to handle LoseThos rich text. Cmds like Dir() and Grep() can output links to the cmd line. -] CMD PROMPT The LoseThos cmd line interface is based on C/C++. Explore the ".CPZ" files. A cmd which takes no args may be executed by typing the name and a semicolon. Cmds with args require placing the arg in parentheses like a function call. Dir("*"); will list files in the current directory. Dir; uses default of "*". Cd("::/LT/Apps"); will change directories. Directories are referenced with "/" not "\". The Boot drive is referred to with "::". Other drives are referred to by a letter and a colon. Your user acct directory is referred to with "HOME". If a file is not found in one directory, all it's parents are searched. Ed("FILENAME.TXZ"); Invokes the editor. See Editor cmds. Note that editor cmds work practically everywhere--like at the cmd prompt or within help. Some cmds like Grep() take a "find_files_mask". They begin with the name of a dir tree and end with a list of filename masks. See FilesFindMatch(). Grep("pattern","/LT/Demo/*.CPZ;*.TXZ;"); Be aware of TEXT_FILE_MASK and SRC_FILE_MASK. -] BURNING CD-ROMs/DVDs 0) Prepare a partition (drive) with the files you wish to burn. 1) Use CDFileCreate() to make an ISO image file of a partition. 2) Use CDImageWrite() to burn an ISO file onto a CD or DVD. Note: You can create a Temp (File Partition) on an ordinary partition, copy files into it, create an image and burn it. Bootable CD-ROMs -] Level 2: ADMIN HELP -] ADDING DRVS Use Mount() to mount disk drives. See Temp File Partition for a special type of "drive".
