How Do I Concatenate Strings in Visual Basic?

Primary Software: Measurement Studio>>Visual Basic Support
Primary Software Version: 7.0
Primary Software Fixed Version: N/A
Secondary Software: Driver Software>>NI-488.2
Hardware: GPIB

Problem:
I am writing a GPIB application in Visual Basic and I would like to be able to build message strings on the fly. How do I concatenate strings in Visual Basic?

Solution:
If you have several strings or variables mixed with the strings, and you want to combine them, you can use concatenation (the ampersand character, &). Here is an example:

String1 = "Sample1"
String2 = "Sample2"
Variable1 = FREQ

The concatenation of the strings would be: "Sample1" & FREQ & "Sample2".

In a simple ibwrt command you would write this as:

CALL ibwrt (ud%, "Sample 1" & FREQ & "Sample"$);
