numbers to which the cursor is to be moved. The next PRINT,
PUT,
GET, INPUT, or LOCATE statements will use this cursor
position. However , DRAWTO, PLOT, and XIO will not use the
new cursor position specified by POSITION.
The cursor will not actually move until a subsequent input or
output command to the screen has been issued.
LOCATE
The LOCATE command positIOns the graphics cursor to the
position specified and returns the code corresponding to the
character or point displayed at that position. LOCATE is used
with the following configuration.
LOCATE column, row, code
row and column specify the screen location. code must be a
numeric variable. The value returned from the position specified
is assigned to the numeric variable named in code.
The code returned by LOCATE is interpreted in the same
manner as the codes used with the COLOR statement. In
graphics mode 0, this code specifies the character being
displayed. Use Table 9-7 to interpret the code returned by
LOCATE in graphics mode O.
In graphics modes 1 and 2, the code indicates both the character
and
the color register used to display that character. Use Table 9-
4
to interpret the code re turned by LOCATE in graphics modes 1
and
2.
In graphics modes 3 through 8, the code returned by LOCATE
identifies the color register in use at the position specified. Use
Table 9-6 to interpret the code ret urned by LOCATE in graphics
modes 3
through 8.
When LOCATE is us ed to read a code from the screen, the cursor
will move one location to the right. If the cursor was on the last
column of a row when LOCATE was executed, the cursor may
