Creating Thoroughbred Basic Methods

Methods may be written in Thoroughbred Basic. Thoroughbred Basic capabilities are described in the Thoroughbred Basic Reference Manual.

Note: Thoroughbred Basic Methods must be maintained in Source-IV.

The scope of this section is limited to an explanation of factors that affect the use of Thoroughbred Basic in OPENworkshop.

Thoroughbred Basic Methods in Source-IV

When creating a Thoroughbred Basic method in Source-IV, specify it as type M.

CONNECT in Thoroughbred Basic Methods

The CONNECT directive is not valid in Thoroughbred Basic, and the Thoroughbred Basic environment will not automatically create and dimension the string arrays used to communicate parameters and messages. The Thoroughbred Basic method must dimension the required arrays and CALL a program as follows:

Note

CONNECT	CALL	ARRAYS
HELP	004, 001Z	HELP$[4]
MENU	001, 001Z	MENU$[3]
QUERY	00R	QUERY$[11]
REPORT	00R	REPORT$[11]
SCREEN	002A	SCREEN$[17]
VIEW	003A	VIEW$[19]
:::

Please see the on-line help for a description of the CALL lists for these calls.

Thoroughbred Basic Language Restrictions

The following directives must not be used in OPENworkshop:

BEGIN
CLEAR
CLOSE
END
FORMAT DELETE ALL
PRINT 'WC', or 'WO'

If a Thoroughbred Basic method needs to open a channel, the UNT function must be used to obtain the next available channel.

CUEXIT is a standard routine, which will close all channels opened by the program, delete any windows, which were created, and set the precision back. For more information, see the Associated Systems section of this manual.
