Filename based on parameter: How can we add a parameter in a filename so that the filename changes, based on the parameter?
 Use the normal &V[varname] notation in the filename, e.g.: Set V[filename] "C:\temp\&V[plantparam]\barcode.txt" OpenFile "&V[filename]" AppendFile ... CloseFile "&V[filename]" By the way, instead of C:\temp you can also use the Windows TEMP-variable; notation is &%[xxx] where xxx is the name of the environment variable: Set V[filename] "&%[TEMP]\&V[plantparam]\barcode.txt"
