Data, Read, Restore
Used to mark the beginning of a data list.
Syntax
Data
list of constants
Read
[VarExpr]
Restore
Remarks
Data
function: A list of floating point constants that can be read (using Read )
into an Array Variable.
Parameter: A list of floating point constants.
Read s Data from Data declaration into an array. Subsequent Read picks up
where current Read leaves off.
Parameter: Variable destination.
Restore pointer to Data to beginning. Used in conjunction with Data and
Read .
Data Statement Example
This example uses Data to hold the data values and Read to transfer the values
to variables.
Data 1, 2, 3, 4, 5 'data for x
Data 6, 7, 8, 9, 10 'data for y
For I = 1 To 5
Read x( I )
Next I
For I = 1 To 5
Read y( I )
Next I
This next example uses Restore to read 1, 2, 3, 4 into both X( ) and Y( )
variables.
Data 1, 2, 3, 4
For I = 1 To 4
Read X( I )
Next I
Restore
For I = 1 To 4
Read Y( I )
Next I
ClockSet (Source).
Sets the CR9000 clock from the values in an array. The most likely use for
this is where the CR9000 can input the time from a more accurate clock than
its own (e.g., a GPS receiver). The input time would periodically or
conditionally be converted into the required variable array and ClockSet would
be used to set the CR9000 clock.
Source
Array
The source must be a seven element array .
array (1).. array (7) should hold respectively year,
month, day, hours, minutes, seconds, and microseconds.
