2.3.15 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 ...) ; When the code is recompiled, CURVER is
automatically assigned the version of the
recompiled code.
