Explanation 
 - Program look-ahead 

When an automatic operation cycle starts, a program is executed as 
described below. 
<1>  The command of one block is read from the specified program. 
<2>  The read command is analyzed and converted to executable data. 
<3>  The command of the block is executed. 
 
During execution of the command, steps <1> and <2> are performed 
for the next block in advance. Upon completion of the current block, 
execution of the next block can be started immediately. This 
processing is referred to as look-ahead or buffering. 
 
The number of look-ahead blocks depends on the processing status or 
parameters.
