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:
AREV
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.
