The name can include absolute or relative path information. The following guide is an instructional walkthrough of fundamental system administration tasks and how to begin programming in the jBASE database. BP Native file C: Checks that an expression consists entirely of printable characters.
Returns the bitwise negation of an integer specified by a numeric expression. Opens the tty device and accepts commands from the keyboard when the jSHELL has been invoked to process a command input file. NOTS function Returns a dynamic array of the logical complement of the elements of a dynamic array. Returns a dynamic array of delimited fields from a dynamic array of strings.
Successively extracts delimited strings from a dynamic array. As the O option Wn set warning level to 0, 1, 2 or 3, see below Ipath path for include files V allow persistent variables in subroutines Qq specifies that the source code contains embedded SQL statements, see below If the record key selection is omitted, BASIC will use any preceding select list. Change file properties 1.
NULL statement Does nothing. This enables query language statements such as: Transfers program execution to a label based upon a calculation. The value is set to YES by default. DIR function Returns information about a file.
No modifications to the application source are required as any operating specific modifications will have been implemented by jBASE in the runtime libraries. In order to be able to rebuild a shared library the object file is retained in the “objdir” subdirectory of the “lib” directory.

Reads a single character from the input buffer and returns it. SEND statement Sends output to a device. Checks that the expression consists of entirely lower case characters. This will ensure conversion of attribute mark characters to new line and vice versa is suppressed thus invalidating the binary object. Beyond this convenient feature, jSHELL also offers many significant advantages over traditional shells and is easier to use.
Create hashed file dictionary only: Reads a record and maps the elements into a dimensioned array. User specific environment variables are set in the home directory. Create a backup for our account 1. Assigns the elements of a dynamic array to a dimensioned array. The higher the warning level the more warning messages will be generated.
NOT function Inverts the Boolean value of an expression.
Checks that an expression consists entirely of alphanumeric characters. This is the default optimization level. Calls can be made to OS functions and vice versa. Converts a latin1 or binary string into the UTF-8 equivalent byte sequence.

Check the result with the jstat command. CATS function Concatenates corresponding elements in two dynamic arrays. It can be invoked as your login shell by using the normal system administration software supplied with the platform.
Creating your demo account for this walkthrough 1. Finds the position of an element in a specified dimension of a dynamic array.
