These configurations allow you to fine-tune the declaration of cursors in the Acu4GL for Sybase product. In general, cursors are declared with the following syntax:
DECLARE cursor_name option_1 CURSOR option_2 FOR <select....> option_3
In other words, different phrases can go in each of the option_X places. Also, different versions of Sybase allow different options in each of those places. Because of this, the Acu4GL product allows customization of the cursor declaration via these three variables. The values of these variables is placed verbatim into the declare phrase when building a cursor. Note that any errors in the values of these variables may cause your Acu4GL product to be inoperable. You should refer to the Sybase documentation to determine what phrases are allowed in each case.
The default values are as follows (limit is 65 characters for each option):
OPTION_1: "SCROLL"
OPTION_2: blank
OPTION_3: "For read only"
Users of Sybase version 11 should set the value of OPTION_3 to "at isolation read uncommitted" in order to prevent page locks.
