There are a couple of knowledge points here.
1) the call symput is obsolete.  call symputx should be used whenever possible. call symputx converts values automatically.
2) using cat class function to do the concatenation for the same reason.

193  data def;
194  length Variable $8 P_value 8;
195  input
196  Variable  P_value;
197  call symputx( catt('P',Variable), P_value);
198  cards;

NOTE: The data set WORK.DEF has 10 observations and 2 variables.
NOTE: DATA statement used (Total process time):
      real time           0.00 seconds
      cpu time            0.00 seconds

211  %put &Pv1 &Pv2 &Pv3 &Pv4 &Pv5 &Pv6 &Pv7 &Pv8 &Pv9 &Pv10;
0.64 0.08 0.06 0.04 0.01 0.01 0.01 0.01 0.01 0.01

thanks  very much~

感谢ziyu老师回答，我晚上上论坛答复你。我用了个笨办法暂时先解决了：用symput弹出十个布尔宏变量，然后最后用宏do和宏if做的累加。

先谢谢，晚上看。
