Re: Open JMP file in read-only mode

The only way to lock from editing via
script is as follows. 

1. establish a pointer to data table
2. switch lock boolean 

// example code snippet
// assumes current table is that which
to be locked
dt = current data table(); 
dt << Lock Data Table(1);
// end code snippet

This will stop editing of data via interface.


Note that this is not fool proof ...
since you can hack around this if you know how. 
All you have to do is to UNLOCK the
data table through the table interface. 

But, if the source file on the network
you work on is controlled via MS Network 
security to prevent overwrite ... then
you can protect editing of the source data that way. 

Alos, I reco for large data sets you
place the data in a MDB or SQL type data base and 
use the ODBC features of JMP to access
the info, this way the source data is controlled.

Subject	[jmp-l] Open JMP file in read-only mode

Does anyone know how to open a JMP data table
in read-only mode using the scripting language?  I need to set the
read-only option within the JMP script and not through the file-properties
options.

Thanks
Dan
