Calling multiple macros within a data _null_ statement

[mgm]

I'm having trouble calling  3 different macros in a sequence within a data _null_ step. Here is a code snippet :

DATA _NULL_;

SET DATES;

if x = 'A' then call execute ('%runA('||rebal||')');

if x = 'B' then call execute ('%runB('||rebal||')');

if x = 'C' then call execute ('%runC('||rebal||')');

run;

Essentially x is in a sequence 'A','B','C','A','B','C','A','B','C','A','B','C'. Since the execute statement runs at the end of the data step there is no guarantee that the three steps are running in the right sequence.  steps in %runB depend on %runA to complete and steps in %runC depend on %runB to complete... 

Let me know ?

Hi @mgm,

The late Roland Rashleigh-Berry recommended to mask macro calls in CALL EXECUTE with %NRSTR in order to prevent premature execution: http://www.datasavantconsulting.com/roland/call_exec.html

So, you could try if 

if x = 'A' then call execute ('%nrstr(%runA('||rebal||'))');

etc. works better.
