help sic delay
SIC DELAY
       [SIC]SIC DELAY Seconds
       [SIC]SIC DELAY
 
   Delay the execution of commands. SIC DELAY is used  in  two  times.  The
   first  call  is  given a duration as argument. Added to the current date
   and time, this defines a virtual milestone in the future. The next  call
   without argument will wait for this milestone if it has not been reached
   yet, or will return without waiting if the limit is already past. During
   the waiting time, CTRL-C can be used to exit the command.
 
   An application of SIC DELAY is to slow down the execution of loops which
   display or draw useful informations to the user. In the  example  below,
   we ensure that the loops are executed every second (or more), instead of
   depending on the CPU speed which varies over machines and epochs:
      FOR I 1 to 10
        SIC DELAY 1.0
        Do something
        SIC DELAY
      NEXT

class 中的sic delay命令可以延迟执行程序

例如我把处理出来的结果放在platform.zcp中啦,我想检查每条谱线,于是我用了sic delay 2.0这个命令,这样没张图片都可以停留两秒,我就能看清楚没张图片啦

file in platform.zcp
find
for i 1 to 500
SIC DELAY 2.0
get i
plot  
SIC DELAY
next i
