My output path is: C:\OUTPUT\ My file name isAPCHECKS9999 where is a counter that gets incremented each time the program is run. FNAME would be C:\OUTPUT\APCHECKS9999 so that my statement would read: OPENSEQ FNAME TO OUTFILE... However, since APCHECKS9999 would be unique each time it doesn't exist. BTW when I try to display OUTFILE it gives me an Unitialized Variable, zero assumed error.

Each record will be a series of fixed-length fields. Each file will need to be created at the time of opening. The destination will be a Windows folder on one of our servers. I will be using OPENSEQ to open the file. However, since each file needs to be created at time of opening what do I use to create the file? My reading of OPENSEQ doesn't indicate that it will create it automatically if it doesn't exist. Thanks.
