Unfortunately, I no longer have access to SQR, but I used to use it a lot.
First of all, the command specified above is SQRWP, not SQRW. That stands for SQR Print. It requires an SPF file as input - it doesn't run SQR, just the converter. Do you have an SPF file? If so, that is the file name that is to be input, e.g. c:\AUD12000.spf SPF stands for SQR Portable File format. SQR always produces one of those first, THEN converts it to the desired output (PDF or Line printer or even CSV).

If you do not have a file with an SPF extension, you should run SQRW with the -KEEP option to create one.

The reason to generate an SPF file is so you can play with the options without having to constantly access the database and do all the processing each time. As I pointed out before, the conversion from SPF to the desired format is done at the end of each SQR run. -KEEP just doesn't delete the SPF file at the end of processing.
By the way, neither here nor there, but the CSV format sucks. It generates an awful output file. I always found it better to use -PRINTER:LP (line printer) and then import it into an Excel file directly and save as CSV. I mean if you must. Do NOT expect it to generate pretty columns of data. When I wanted nice columnar output, I used to write headers and column data with commas in between as a separate file and not use the report formatting, but that's a lot of additional work.
Hope this helps.
