MWAPI - SCROLLBY

1995 Version of ANSI (Equivalent to Current ISO Version) of Standard

SCROLLBY specifies the amount by which the VALUE elattribute increases or decreases when the user presses a scroll gadget’s movement control. If the user presses a small movement control, the scroll gadget’s VALUE elattribute is increased by the amount specified by the scrollsmall component of the SCROLLBY value. If the user presses a large movement control, the scroll gadget’s VALUE elattribute is increased by the amount specified by the scrollbig component of the SCROLLBY value.

If an application attempts to assign a scrollby value that contains a negative value for scrollsmall or scrollbig, an error occurs with $ECODE containing ",M?2," and $EREF containing a value that indicates the ssvn reference for which the error occurred.
