Useful for reformatting data from a family of test forms, linked by a network of common items, into a single common structure suitable for one-step item banking.
RFILE=filename outputs a file which contains a scored/keyed copy of the input data. This file can be used as input for later analyses. Items and persons deleted by PDFILE= or the like are replaced by blank rows or columns in the scored response file. The file format is:
1. Person-id: 30 columns wide or maximum person-id length, whichever is larger.
2. Responses one per item:
One column for each response if largest scored response is less than or equal to 9.
Two columns for each responses if largest scored response is more than 9.
Missing or unscored data are indicated by "."
The width of the responses is not determined by XWIDE=.

Example: I have 9 scored items. for example LP1, LP2, CS1, CS2, CS3, D1, R1, R2, TE1. I would like to combine the following into one subtest (LP1 and LP2) and (CS1,CS2,CS3) and (R1 and R2) using Winsteps. D1 and TE1 will remain unchanged. This means I will ultimately have 5 items LP, CS, D, R, and TE.
Winsteps cannot combine items automatically. So here is a suggestion if your data file is already in Winsteps format:
1. Launch Winsteps
2. Analyze your 9-item file
3. Winsteps menu bar, "Output Files", Output the RFILE= to Excel
4. In Excel, combine your items into subtests
5. Winsteps menu bar, "Data Setup", convert your Excel file into a new Winsteps control file
6. Analyze the new Winsteps control file.
