Debug information is produced for the jBC debugger but not for the C debugger. Replace substring in an expression with another substring.

INTRODUCTION TO jBASE

Where are the subroutines? The jrestore can be controlled to restore from any file type on the backup, from single records to multiple directories. LEN function Returns the character length of an expression.

In order to be able to rebuild a shared library the object file is retained in the “objdir” subdirectory of the “lib” directory. DIVS function Divides corresponding elements in two dynamic arrays. Subroutine object files are collated into evenly sized shared libraries and then by default placed in the home directory “lib” directory.

Returns and internal time using the specified Timestamp and TimeZone combination. Defines a heading to be included at the top of an output page. For example, to set warning level 3 use the following command: NUM function Returns Boolean true if the supplied value is numeric. Checks that an expression consists entirely of control characters. Create a dynamic array of logical AND of corresponding elements from two arrays. Transfers the contents of a dimensioned array to a specified record on disc.

Tests if elements of one dynamic array are equal to the elements of another dynamic array. The LOG parameters set or clear the flag which allows the file to be included or excluded when utilizing the item or transaction logging mechanism, if licensed on your system.

Assigns the elements of a dynamic array to a dimensioned array. TRIM function Removes characters from a string. Application and OS commands use environment variables to aid in their execution. Opens the tty device and accepts commands from the keyboard when the jSHELL has been invoked to process a command input file. Dumps a portion of the application to an external file for later analysis.

Passes data back to the primary input buffer of a calling jCL program.

Writes a block of data to a file opened for sequential processing. The value is set to NO by default. GET statement Gets input from an opened serial device. No debugging information is produced.

T TAN function Commande the tangent of an angle. Transfers the contents of a dimensioned array to a specified record on disc and preserves locks.

The jsh will default to the previous emulation used by the current port. Turns off buffering for a file opened for sequential processing.

SMUL comands Performs string multiplication. Attempts to lock an entire file for exclusive use by this program. WEOF statement Writes an end of file mark on an attached tape device.

In our example below we will be using C: All symbol information is removed from the final executable and all available safe optimizations are performed by the resident C compiler. Some Operating Commansd require large file comands to be enabled when the file system is created. In same manner, quoted strings such as “quoted string” are passed directly to the command with quotes intact.

Creating your demo account for this walkthrough 1. Converts a latin1 or binary string into the UTF-8 equivalent byte sequence. Returns the interval between two timestamps as a dynamic array.

LES function Determines whether elements of one dynamic array are less than or equal to the corresponding element in another dynamic array. Please fill out the contact form below and we will reply as soon as possible. NULL statement Does nothing. Reads a record from an opened file into a variable respecting locks. In this case, the record-list is ignored. Counts the number of elements in a string separated by a specified delimiter. Returns the decimal representation of a hexadecimal expression.

ABS function Returns absolute value. Converts the elements of a dynamic array to external format. How can we help you? Some of the main features of the jsh are: FMTS function Formats the elements of a dynamic array for output.

Calculates the value of the quotient after division of the dividend by the divisor.
