Using an include mask in -filemask switch is indeed partially redundant to the "wildcard". But the -filemask switch allows also exclude masks and path-specific masks, or you can easily use it to download all files of certain type recursively.

The failonnomatch indeed does not work for -filemask switch.

I have added this to the documentation:

Anyway, there's no reason to use the -filemask switch for your particular needs. Just use:

get "/835s/*.835>1D" c:\users\username\desktop\

Thanks for the clarification. In reading filemask documentation it doesn't seem clear to me when it would be appropriate to use the filemask switch versus putting the mask in the filename as you suggested. Would you explain?

Version is 5.7.3 (Build 5438)
The problem did not originate with upgrade. This is the first time using this feature.
OS is Windows 7 Enterprise
Transfer protocol is SFTP
I am using scripting.
I do not get any errors.

I expect WinSCP to report no match in the event a .835 file newer than one day is not found and return a non-zero exit code however it returns success. Removing the filemask switch causes the script to report no match if there are no .835 files. I need to know if there is a match newer than one day or not.

Here is the command line:
winscp.com /ini=nul /script=scriptFile /xmllog=logFile

Here is the script:
option batch on
option failonnomatch on
open sftp://user:password@sftp.server.com/ -hostkey="ssh-dss 1024 bb:e6:a2:bc:57:02:f6:38:85:6d:ca:b3:5a:f6:35:91"
get -filemask=">1D" "/835s/*.835" c:\users\username\desktop\

This is what I see running these commands in the console:
C:\Users\username>winscp.com
winscp> option batch on

reconnecttime 120
winscp> option failonnomatch on
