SCR_YLIM

Syntax	SCR_YLIM [(#ch)]
Location	SMSQ/E

This function is the same as QFLIM(#ch,1) except that the channel parameter is optional (it defaults to #0).

NOTE

As with SCR_BASE, if the specified channel is not open then Invalid Channel ID will be reported. However, if no channel is specified and #0 is not open, then a special window will be opened for #0 on screen, which may destroy what is already on screen.
