reg filename validations

[crux123]

Hi,
I am working on a scenario where in I have got a control file (control.txt) whose contents are some filenames
(say for eg file1.txt , file2.txt,file3.txt etc) .
These text files are actually also present say in my map directory for example.

Thus based on the control file contents , i want my map to validate whether these data files are actually available in the map directory.

Any suggestions are welcome.

Regards

Hello,

Which operating system will this(map) be executed. Please mention that.

Thanks,

Try using GET with the VALID command wrapped around. If the GET works, then the file exists.

This might be a better solution as it does not load the file.
In Windows use the rule

=GET("BAT","-cli -cmd 'dir c:\dirlist.txt' /B") /*how to run a batch command in a rule

If it finds the file it returns the file name. If the file is missing it returns nothing.
For generic use substitute the hard coded file name with the input card file name.

Or you could do this

valid(GET("BAT","-cli -cmd 'dir c:\dirlist.txt /B'"),"missing")
