Writing to the same log file

[Aditi24]

Hi,

I have two sas programs both are trying to write the log to same external file in succession. First program A will write to the log file and then program B has to append its log to the same external file. Please suggest me a way to do so.

You actually have two problems to solve.  You also have to ensure that program A completes before program B begins.  The easiest way to do that is to create program C to run both A then B:

%include 'program_a.sas';

%include 'program_b.sas';

There are other approaches that involve PROC PRINTTO, but %INCLUDE should be easiest and safest.
