 +====== Chapter B 4 : Logging On to Advanced Revelation ======
 + 
 +This chapter explains how to enter Advanced Revelation by logging on. It also describes the 
 +use of logon options to invoke special Advanced Revelation processing modes. 
  
 +===== Logging On to Advanced Revelation =====
 + 
 +Once Advanced Revelation has been installed, you may log on. Access the subdirectory 
 +containing the Advanced Revelation files and the AREV.EXE file (C:\AREV, if you installed 
 +Advanced Revelation using the defaults in the Installation process). Then, from the operat- 
 +ing system prompt enter: 
 +
 +<code>
 +AREV 
 +</code>
 +
 +If you are using Advanced Revelation for OS/2, you can log into more than one session on a workstation. Just initiate another session using the Session Manager, and log 
 +in again. The number of Advanced Revelation sessions you may run on a workstation is limited only by the amount of memory available. 
 +
 +===== Using Logon Options =====
 + 
 +Depending on your computer’s hardware and software configuration, you may want 
 +to log on to Advanced Revelation using one or more logon options. These options 
 +activate special Advanced Revelation modes that support a variety of processes. 
 +
 +^Option^Function ^
 +|E|Activates math coprocessor emulation |
 +|S|Suppresses display of the logon banner| 
 +|x|Activates expanded memory support in Expanded mode: any string over 508 bytes is swapped to expanded memory as necessary|
 +|0|Entirely de-activates expanded memory support|
 +|+ Mnnnn| Allocates a specific amount of expanded memory for use by Advanced Revelation. nnnn is the number of kilobytes of expanded memory initially allocated. |
 +|Hnnn|Changes the number of file handles available to Advanced Revelation. nnn is the number of file handles. |
 +
 +For more information on LIM EMS 4.0 logon options, see the chapter “Using 
 +Expanded Memory” later in this section. 
 +
 +For more information, see the chapter “The dBASE III Environmental Bond” 
 +in Environmental Bonding. 
 +
 +==== The E Option ====
 +
 +In certain isolated circumstances, Advanced Revelation does not 
 +receive a correct response when checking for a math coprocessor. 
 +If this is the case, these computers will sometimes “hang” or fail 
 +to continue processing and may display the error message “Divide 
 +overflow” or “Stack overflow”. To correct the problem, append /E
 +to your logon command. This causes Advanced Revelation to load 
 +a software emulator of the math coprocessor. 
 +
 +==== The S Option ====
 +
 +To suppress the logon banner that normally displays while the 
 +system is loading, append /S to your logon command. 
 +
 +To specify one or more options in the logon command, type in the command as 
 +usual. Then enter your options, preceding each with a/ (forward slash). For 
 +example: 
 +
 +</code>
 +AREV SYSPROG /E/X 
 +</code>
 +
 +logs the user into the SYSPROG account, turns on math coprocessor emulation, and 
 +invokes expanded memory in Expanded mode. 
 +
 +==== User Name Assigned at Logon ====
 + 
 +Advanced Revelation can detect whether your computer has a monochrome or 
 +color/graphics monitor. When logging in, if you specify neither a user name nor an 
 +account name, Advanced Revelation assigns you a user name: 
 +
 +  * If you have a color or graphics board, or if you are using Advanced Revelation for OS/2, you will be logged in as the user COLOR.USER. 
 +  * If you have a monochrome monitor, you will be logged in as the user USER. 
 +
 +For more information on user and account names, see the chapter “About Users and 
 +Accounts” in Developing an Application. 
 +
 +==== Setting the Help Level ====
 + 
 +The first time you log on to Advanced Revelation, you will see a popup window that 
 +asks you to set.a help level. Your help level dictates which version of the status line 
 +appears at the bottom of the screen. Setting the help level to 2 (New user) provides 
 +a status line listing active function keys. A help level of 0 (Advanced user) displays 
 +the full status line. 
 +
 +To make a selection from the popup, use the arrow keys to move the highlight bar. 
 +Set the highlight bar on your choice, and press [Enter]. 
 +
 +For more information on the use of help levels, see the “Using System Features” 
 +chapter in Getting Started.
