14.8.2
Substitution characters
The system offers the option of defining control properties (attribute values) for the runtime. In order to use this function, the
desired property must be set in a local variable and the variable name must be transferred to the tag as an attribute value
preceded by the
character $
.
If the tag expects a string as attribute value or value, the $$$ characters must be placed in front of the variable name.
Example:
<let name="my_ypos">100</let>
<let name="field_name" type="string"></let>
<control name = "edit1" xpos = "322" ypos = "$my_ypos" refvar="nck/Channel/Parameter/R[1]"
/>
<op>my_ypos = my_ypos +20 </op>
<control name = "edit2" xpos = "322" ypos = "$my_ypos" refvar="nck/Channel/Parameter/R[2]"
/>
<print name =" field_name" text="edit%d">3</print>
<op>my_ypos = my_ypos +20 </op>
<control name = "$field_name" xpos = "322" ypos = "$my_ypos"
refvar="nck/Channel/Parameter/R3]" />
<caption>$$$field_name</caption>
