mv_jobwaitfor is updated to allow the log to be fetched for all the submitted jobs.

+  @file
+  @brief Extract the log from a completed SAS Viya Job
+  @details Extracts log from a Viya job and writes it out to a fileref
+
+  To query the job, you need the URI.  Sample code for achieving this
+  is provided below.
+
+  ## Example
+
+  First, compile the macros:
+
+      filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
+      %inc mc;
+
+  Next, create a job (in this case, a web service):
+
+      filename ft15f001 temp;
+      parmcards4;
+        data ;
+          rand=ranuni(0)*1000;
+          do x=1 to rand;
+            y=rand*4;
+            output;
+          end;
+        run;
+        proc sort data=&syslast
+          by descending y;
+        run;
+      ;;;;
+      %mv_createwebservice(path=/Public/temp,name=demo)
+
+  Execute it:
+
+      %mv_jobexecute(path=/Public/temp
+        ,name=demo
+        ,outds=work.info
+      )
+
+  Wait for it to finish, and grab the uri:
+
+      data _null_;
+        set work.info;
+        if method='GET' and rel='self';
+        call symputx('uri',uri);
+      run;
+
+  Finally, fetch the log:
+
+      %mv_getjoblog(uri=&uri,outref=mylog)
+
+  This macro is used by the mv_jobwaitfor macro, which is generally a more
+  convenient way to wait for the job to finish before fetching the log.
+
+
+  @param [in] access_token_var= The global macro variable to contain the access token
+  @param [in] mdebug= set to 1 to enable DEBUG messages
+  @param [in] grant_type= valid values:
+    @li password
+    @li authorization_code
+    @li detect - will check if access_token exists, if not will use sas_services if
+        a SASStudioV session else authorization_code.  Default option.
+    @li sas_services - will use oauth_bearer=sas_services.
+  @param [in] uri= The uri of the running job for which to fetch the status,
+    in the format `/jobExecution/jobs/$UUID/state` (unquoted).
+  @param [out] outref= The output fileref to which to APPEND the log (is always
+  appended).

+/**
+  @file
+  @brief Extract the log from a completed SAS Viya Job
+  @details Extracts log from a Viya job and writes it out to a fileref
+
+  To query the job, you need the URI.  Sample code for achieving this
+  is provided below.
+
+  ## Example
+
+  First, compile the macros:
+
+      filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
+      %inc mc;
+
+  Next, create a job (in this case, a web service):
+
+      filename ft15f001 temp;
+      parmcards4;
+        data ;
+          rand=ranuni(0)*1000;
+          do x=1 to rand;
+            y=rand*4;
+            output;
+          end;
+        run;
+        proc sort data=&syslast
+          by descending y;
+        run;
+      ;;;;
+      %mv_createwebservice(path=/Public/temp,name=demo)
+
+  Execute it:
+
+      %mv_jobexecute(path=/Public/temp
+        ,name=demo
+        ,outds=work.info
+      )
+
+  Wait for it to finish, and grab the uri:
+
+      data _null_;
+        set work.info;
+        if method='GET' and rel='self';
+        call symputx('uri',uri);
+      run;
+
+  Finally, fetch the log:
+
+      %mv_getjoblog(uri=&uri,outref=mylog)
+
+  This macro is used by the mv_jobwaitfor macro, which is generally a more
+  convenient way to wait for the job to finish before fetching the log.
+
+
+  @param [in] access_token_var= The global macro variable to contain the access token
+  @param [in] mdebug= set to 1 to enable DEBUG messages
+  @param [in] grant_type= valid values:
+    @li password
+    @li authorization_code
+    @li detect - will check if access_token exists, if not will use sas_services if
+        a SASStudioV session else authorization_code.  Default option.
+    @li sas_services - will use oauth_bearer=sas_services.
+  @param [in] uri= The uri of the running job for which to fetch the status,
+    in the format `/jobExecution/jobs/$UUID/state` (unquoted).
+  @param [out] outref= The output fileref to which to APPEND the log (is always
+  appended).
