        desVar("vout" vout_name)

temp(temp_name)


run()

idx= OP("/M1","id")
title=sprintf(nil "%g" vout_name)   我觉得这里有问题！！！！

fp=outfile("/home/aaa/script/newfile.txt" "a")
fprintf(fp "%s: \t %g \n" title idx)
close(fp)
)
)
)
)

load "ocean.ocn"时，报错*Error* fprintf/sprintf: format spec. incompatible with data - 0
我觉得错误出在title=sprintf(nil "%g" vout_name)    求问这个错误是怎么回事？
