Ass
Associates a variable tag with a Super Genie. This association is only made for the next Super Genie you display (either in the current window or in a new window). You cannot create an association for a Super Genie that is already displayed. You needs to call this function once for every Super Genie substitution string in the Super Genie, otherwise the variable (substitution string) will remain uninitialized and it will be displayed as #ASS.
This function provides the lowest level of support for associating Super Genie variables with physical tags. The higher level functions (listed below) are simpler to use.
Syntax
Ass(hWin, nArg, sTag, nMode [, ClusterName] )
hWin:
The association will be created for the next Super Genie to display in the window specified here; enter the window number or:
nArg:
The argument number or name (substitution string number or name) of the Super Genie string to be replaced by sTag. For example, to replace ?INT 3? with sTag, set nArg to 3 ,or ?Level? set nArg to Level.
sTag:
The variable tag that will replace the Super Genie substitution string. The tag needs to be the same data type as that specified by the Super Genie substitution string. For example, only a digital tag could replace the substitution string ?DIGITAL 4?. Any other type of tag may raise a hardware alarm or display #err. If the substitution string does not specify a type (for example, ?5?), you can use any type except STRING.
The name of the tag can be prefixed by the name of the cluster for example, "ClusterName.Tag".
nMode:
The mode of the association. Set to 0.
ClusterName:
Specifies the name of the cluster in which the Variable Tag resides. This is optional if you have one cluster or are resolving the tag via the page's current cluster context. The argument is enclosed in quotation marks "".
Resolution of the tag's cluster context occurs when the page is displayed. It is resolved to the page's cluster context, not the context in force when this function is called.
Return Value
0 (zero) if successful, otherwise an error is returned.
