Hello everyone,

I'm reading code with the following lines :

Code:

   MVC   VAR1,0(R10)           
   IF    (VAR1,EQ,C'D'),A125
   IF    (VAR2,EQ,=C'FD1'),(VAR2,EQ,=C'1B2')
      THEN
         MVC   VAR3,VAR4
   ENDIF


Can anybody please tell me where I can find help on the IF, THEN and ELSE macros ?

all depends on whose code it is ( if third parti code You will have to ask them )
and where the <structured programming macros> were obtained.

if they are the ones from the HLASM TOOLKIT they ARE documented in the HLASM TOOLKIT user guide here ( for example )
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ASMTUG20/CCONTENTS?SHELF=ASMSH030&DN=GC26-8710-09&DT=20080715202826

otherwise You will have do some researching Yourself inside Your organization

@ hbdivers

Have a look at the MACLIB, Makro-Libraries.
Browse the EIF Member for example. There you could find:

MACRO

These Makros belong to the very old SPL Environment for Assembler.
SPL = Structured Programming Language Einvironment.
