New commands jbase and jb which simplify the login process.

2. Previous Release Behavior


3. Current Release Behavior

3.1. jbase / jb commands

jbase (or its synonym jb) is a small shell script, or Windows .cmd file, that sets up the jBASE system environment and runs the jlogin command. It can be used to start a jBASE session in the following ways:

For simple jBASE installations, it provides a quick way to start a jBASE session without any special configuration.

The jBASE system environment variables are initialized by running (Unix) or jbase_env.cmd (Windows) in JBCRELEASEDIR. On Unix, symbolic links to these scripts are added to /usr/local/bin. On Windows, since %JBCRELEASEDIR%\bin is normally in the PATH, these scripts are already accessible.

The command syntax for jbase or jb is identical to that of jlogin, described next.

3.2. jlogin

The jlogin command is used to initiate a jBASE session. Since jlogin is a jBASE program, the jBASE system environment variables must be set up before invoking this program. jlogin is normally invoked by the jbase or jb scripts, however, if the jBASE system environment variables have been set up, jlogin may be used on its own.


This form will prompt:

Account name or path:

Enter the an account name defined in the SYSTEM file, or enter a relative or absolute path to the directory containing the account files. If an account name is entered, a password (if one is used), can be appended to the name, separated by a comma.

jlogin AccountName

The AccountName must be defined in the SYSTEM file. If there is a password defined for the account in the SYSTEM file, jlogin will prompt:


Enter the password to complete the login. jlogin will set up the jBASE environment based on information in the account record in the SYSTEM file, then start a jShell or the program defined in the SYSTEM record.

jlogin AccountName,Password

This form of jlogin is identical to the previous, except no password prompt is issued.

jlogin AccountPath

When a relative or absolute path is specified, jlogin checks that the target directory is a valid jBASE account. If it is not a valid jBASE account then the following warning is displayed

“AccountPath” does not appear to be a jBASE account. Use the CREATE-ACCOUNT command to create a jBASE account.

Are you sure you want to launch jBASE in this directory?

When an account path (not an account name) is specified, jlogin sets the following environment variables for the account, changes the current directory to the account path and starts a jShell:

        HOME            AccountPath, converted to an absolute path
        PATH            AccountPath/bin is prepended to the current PATH
        JBCOBJECTLIST   AccountPath/lib
        JEDIFILEPATH    AccountPath
        JEDIFILENAME_MD AccountPath/MD if MD file exists; AccountPath/MD]D if it exists; otherwise not set

For convenience, when an account name (not an account path) is used, if the name does not exist in the SYSTEM file, jlogin checks for a SYSTEM record using the upper-case or lower-case form of the account name. If a SYSTEM record using the upper- or lower-case name is found, jlogin will prompt:

Log in to account AlternateAccountName instead?


The following examples are using the jbase command; the jb command could be used in an identical manner. The jlogin command could also be used if the jBASE system environment has been set up.


Prompts for account name or path.


Log in to the JBASEADM account, as defined in the SYSTEM file. If JBASEADM requires a password, it will be prompted.


Log in to the password protected WAREHOUSE account, as defined in the SYSTEM file, with the required password “SECRET”.

jbase .

Set up jBASE account environment for the current directory and run the jsh (jShell) command.


Change the current directory to C:\jBASE\PAYROLL, set up account environment variables for this directory and launch a jShell.
