4.8.2.1 Selecting a Recipe
All recipes are assigned a number from 1 to 250 when they are programmed.
You can select a recipe as follows:
- By means of a fixed assignment between the recipe and a mask. Whenever this
mask is opened, the recipe window will contain the recipe that was specified when
the mask was originally programmed. If a fixed assignment to a recipe has not
been defined when the mask with the recipe window was programmed, the last
recipe that was processed appears in this window when the mask is opened.
- By means of the system variable SelectRezeptNr. This variable can be edited
using any Editor. It is a good idea, however, to use a selection text and assign
meaningful names to each recipe number.
4.8.2.2 Selecting a Data Set
Data sets can be assigned both a number from 1 to 250 and a name.
The data set numbers and names are allocated when the data sets are created, in
other words either in the programming system for data sets stored in the Flash
memory or on the terminal in the case of data sets stored in the RAM. The maxi-
mum data set name length is 15 characters. Data set names need not necessarily
be unique (though it is recommended that they are).
A data set can be selected in one of the following ways:
-
By selecting a new recipe. The associated data set with the lowest number is
then selected for it automatically.
- By means of the system variable SelectDSNr. This variable can only be edited
as a selection text. In this case, only the numbers of those data sets that are
available for the active recipe are displayed.
- By means of the system variable SelectDSName. This variable can only be
edited as a selection text. In this case, only the names of those data sets that are
available for the active recipe are displayed.
4.8.2.3 Copying a Data Set
Only the active data set can be copied. To do so, the number of the destination data
set is written to the system variable DestDSNr and then the value 1 to the system
variable DSCopy.
The following conditions must be fulfilled in order for the data set to be copied
successfully:
-
The number of the destination data set must be between 1 and 250 (DSCopy = 2
searches for a free data set, while DSCopy = 3 overwrites the existing data set).
- There must not already be a data set with the same number for the active recipe
(unless DSCopy is set to 3).
- The active data set can not be edited at the same time.
- There must be enough free RAM on the terminal.
If any of these conditions is not satisfied, the data set is not copied and a system
error message is output.
