Variables
5.13 CURPOS variable
5.13 CURPOS variable
Description
Using the CURPOS variable, it is possible to display or manipulate the position of the cursor
in the active input field of the current dialog. The variable indicates how many characters are
located in front of the cursor. If the cursor is located at the start of the input field, then
CURPOS assumes the value of 0. If the value of CURPOS is changed, then the cursor is
positioned at the appropriate location in the input field.
In order to be able to respond to changes in the variable value, it is possible to monitor for
changes using a CHANGE block. If the value of CURPOS changes, then a jump is made to
the CHANGE block and the instructions contained there are executed.
5.14 CURVER variable
Description
The CURVER (CURrent VERsion) property allows the programming to be adapted in order
to handle different versions. The CURVER variable is read-only.
Note
Even if previously recompiled with an older version, the code is automatically generated with
the most recent version. The "GC" command always generates the most recent version. An
additional identifier indicating the generated version is inserted in the user comment of the
generated code in versions > 0.
Rules
The most recent dialog with all its variables is always displayed.
● Variables used previously may not be changed.
● New variables are inserted in the existing (cycle) programming in arbitrary order.
● It is not permissible to delete variables from a dialog from one version to the next.
● The dialog must contain all variables of all versions.
Example
(IF CURVER==1 ...)
68
; When the code is recompiled, CURVER is
automatically assigned the version of the
recompiled code.
