The Keil supports the version control with Visual Source Safe 8?
If yes, how can I do this?
We never tried this combination (since VSS is not very popular anymore). However there are config files for older versions.
For example: C:\Keil\UV3\Microsoft Visual SourceSafe6.SVCS
The usage (configuration) is explained under: http://www.keil.com/support/man/docs/uv3/uv3_ut_usingsvcsmenu.htm
