Thanks.
I had a typo, actual command is SET DEFAULT TO (m.gcDefDir)

This an existing application original code in FPW 2.6 rewritten by several people and old code got carried forward.

>>I an not sure if I do not understand the set default command or if this is a bug.

>>I determine the default directory and assign it to a variable, i.e
>> m.gcDefDir = SUBSTR(SYS(16,0),1,RAT('\',SYS(16,0)))
>> i.e 'c:\defdir'
>>Then I a set the default directory using the command
>> set default to m.gcDefDir
>>The command
>> ? set("default)
>>returns "C:" instead of "c:\defdir". Is that correct? If not what am I doing wrong?
