RE: Data file mapping in Visual COBOL

I tested this under Net Express 5.1 and Visual COBOL 2.3 and it works perfectly with the preceding $. Without the $ it fails in both as it will not know that CNV is an environment variable so will not expand it.

I tested using the following program where I am setting CNV=C:\temp\ in Net Express project properties-->IDE and in Visual COBOL under Project Properties-->Application-->Environment Variables. The file chris.txt exists in C:\TEMP
