如何把数据集中的值替换并输入到txt文件中

Answer 1

the macro variable temp created by call symput('temp', _infile_);
can not be used (by &temp) in the same data step.

It can be referenced after the data step have finished.

Don't know how to remove the warning. But the file 1234.txt was created correctly with maximum length of 10004.

There is not warning this way.

data _null_;

infile "F:\MySAS\Temp\output\long_string.txt" LRECL=32767;

file "F:\MySAS\Temp\output\12345.txt" LRECL=32767;

length x y temp $11000.;

retain temp;

if _n_ = 1 then do;

input;

temp = _infile_;

end;

set aaa;

p = find(x, 'abc');

if find(x, 'abc') then y= cats(substr(x, 1, p-1), temp, substr(x, p+3));

else y = x;

put @1 y;

run;
