.

string

logs you on, runs the GD INI command, restores the string table named string, and runs all strings in that table with names that begin with string


Remarks

You should always logon because your user name and project number are recorded with scheduler entries (SKE command), string tables (TU command), and some data files (e.g., grid, and MD files). The user name and project number are also checked when a scheduler entry is run and when you request data from a remote server. At startup or after running the LOGOFF command, the user name is set to USER and the project number is set to 0. If you fail to log on with a valid name and project number, you may be prevented from accessing data on some remote servers.


Examples

This entry logs you on to the McIDAS session as user TOM with project number 1234. It also runs GD INI to set the graphics parameters (width, dash and gap) to their initialized values. Otherwise the McIDAS session is left in its present state.

It runs TU REST TOM to restore the string table TOM, and runs all strings in that table with names that begin with TOM, for example, TOM, TOMSDATA, TOMLIST.

LOGON TOM 1234 PLOT
