status & sstatus

status(s_name):
Returns the value of the internal system variable named (s_name). This is an nlambda function.
e.g.


The status function gets a switch. The sstatus function sets a switch.

sstatus(debugMode t)

.oceanrc file

$   ocean

This command loads and reads your .cdsinit file first and then loads and reads the .oceanrc file. You can place OCEAN commands in your .oceanrc file, which is similar to the .cdsinit file.

; graphicsOff()/graphicsOn() helps eliminates the redraw for each plot.
; When graphicsOn() is called, the completed plot appears.
