Prefix values to variables in your XpressDox Document Automation template
The AppendVr and PrependVr functions provide less cumbersome syntax for appending or prefixing values to variables than using SetVr to do this.
Without the use of AppendVr and PrependVr:
Prior to these two functions, suppose you wanted to concatenate a pipe symbol (|) and a data element value (data element Name) to the end of a variable called List. This would be done as:
Simpler with AppendVr and PrependVr:
Using AppendVr, the same thing is accomplished like this:
PrependVr works in an analogous way, but inserts the values in front of the value of the variable:
will put the value of data element «Name», followed by a pipe, in front of the value of variable ‘List’.
Be aware that both of these functions will remove the entire paragraph in which they appear from the merged document. Just as SetVr does.
