In PRO/5, VPRO/5 4.10, and BBj 3.01 and higher, this function returns the license expiration date in Julian date format (binary string). 2147483647 ($7fffffff$) indicates a permanent license or that BBj or PRO/5 is running without a license.

Example 1:

10 LET A=DEC(INFO(2,6))-JUL(0,0,0)
20 IF A<30 THEN PRINT "This license will expire in",A," days"

Example 2:

10 LET A=DEC(INFO(2,6))
20 IF A=2147483647 THEN PRINT "This license will not expire"
20:ELSE PRINT "This license will expire on ",DATE(A)

In PRO/5, the expiration date applies to the license checked out when starting PRO/5. If the license was updated after PRO/5 was started, then PRO/5 must be restarted to return the updated expiration date.

2,7

Not available in PRO/5.

2,8

In BBj 15.0 and higher, whether the SAM license feature is available.

Not available in PRO/5.

In BBj 22.0 and higher, this function returns the expiration date for the SoftwareAssetManagement (SAM) license in Julian date format (binary string).

Example:

LET A=DEC(INFO(2,9))-JUL(0,0,0)
IF A<30 THEN PRINT "The SAM license will expire in",A," days"

3,0

Unique task ID (4-byte binary string).

Four-byte process ID.

3,1

Unique task ID (8-byte binary string).

Eight-byte string, where the first four bytes are identical to INFO(3,0). The last four bytes are set to the local IP address if network access is enabled using SETOPTS byte 4, bit $20$. If network access is not enabled, the last four bytes of INFO(3,1) return $00000000$.

3,2

User name.

User login ID. This value is set to the credentials used at login when user authentication is enabled for BBjServices. BBj initializes this value with the USERID environment variable or the -u option at invocation when user authentication is not enabled in BBjServices. This value can be changed at runtime to change the user for the BBj session by changing the !DSUDDB STBL value:
      void$=STBL("!DSUDDB","user=theuser,passwd=mypassword").

See also BBj User Authentication.

3,3

On Unix, user description (as found in the password file gecos (comment) field.

On Windows, returns the value of the USERDESC environment variable.

User description.

3,4

(Unchanged)

Current host name.

3,5

(Not implemented)

Features of licensed product.

3,6
 

Notes:

• (1) BBj's default behavior is to run as if -TC is set.

• (2) Web start may detect BBjServices running on the client machine. If it determines that it should reuse the JVM used by BBjServices, INFO(3,6) instead returns "1" because the client has the capabilities of a normal thin client session.

Not supported in PRO/5.

3,7

If running in thin client, returns the host name of the client, otherwise returns the empty string.

Not supported in PRO/5.

3,8

If running in BUI (BBj 11.0 and higher) or DWC (BBj 22.0 and higher), returns the navigator.userAgent string from the browser, otherwise returns the empty string.

Not supported in PRO/5.

3,101

(Not implemented)

Novell NetWare: Volume or drive PRO/5 was invoked from, minus the final colon.

3,102

(Not implemented)

Novell NetWare: Full path of the PRO/5 executable, minus any server or volume information.

4,*

Returns operating system environment variables.

Values of any environment variable set. int ranges from zero to the maximum number of environment strings, minus one. In BBj 4.0 and higher, if SETOPTS bit 8, $08$ is set, then the function returns client side environment variables. Otherwise, server side variables will be returned.

6,0

Name of the GUI system, if applicable. This will be one of the following values:

Name of the GUI system, if applicable. This will be "WINDOWS" (Visual PRO/5) or " " (No GUI capabilities).

6,1

Returns a meaningless value. START size is not relevant in BBj.

A binary string containing the maximum possible START size, in 256-byte pages. This value does not indicate the exact amount of memory available, and it may not be possible to use a START size as large as the returned value.

6,3

(Unchanged)

Number of significant digits (as a binary string) for Business Math fields.

7,*

BBj 3.01 and higher: returns operating system environment variables from the thin client side of a thin client session.

Values of any environment variable set on the thin client side. int ranges from zero to the maximum number of environment strings, minus one.

8,*

In BBj 4.0 and higher, returns operating system environment variables from the server side of a thin client session.

Values of any environment variable set on the server side. int ranges from zero to the maximum number of environment strings, minus one.
