Symbolgen option sas macros

These facilitate the validating person, as well symbolgen option sas macros another programmer, taking over the macro development, to quickly understand the code. The main question is: A macro may use SAS system options and set them to specific values irrespective of the values up to the macro call.

Once written they serve to save the user a lot of work and time, they limit the chances on programming errors and they promote standardization of output, whether that consists of datasets or tables, graphs and the like. Thus if the condition is not true then the PUT statement is not generated, but the ending semicolon is; it then just is an empty statement without any consequences. Furthermore these macros still should be extended with code that, next to check for existing dataset or variable names, should also check for already generated random names which are not yet in use as a dataset or symbolgen option sas macros name. A list of called auxiliary macros should be part of the description with per macro symbolgen option sas macros indication of:.

If it has been programmed fool proof it should react to any inconsistency in a user friendly way with a clear error message and abort symbolgen option sas macros producing any results if possible. These should be verified for correctness and possibly checked against other known correct results. Black box testing also tries to check legal, comparable, complex, but yet unknown situations to see whether the macro is suited for those too, while fool proof testing tries to crash the macro, while it never should.

This macro is being used, called later in the macro in the same way and where otherwise the complex macro variable would be specified to perform the macro symbolgen option sas macros and to generate the conditional SAS code. Attached macros have a fixed definition, are called only from the main macro and are specific for that main macro. If it does a new one should be generated and checked for its existence.

This looks similar to declaring all used variables which is obliged in several programming languages. The user of the macro explicitly is encouraged to specify the version number in the macro call to ensure that version to run always, also after new symbolgen option sas macros have become symbolgen option sas macros The user can verify the valid status of the signature by checking it with the macro source code against the known public key of that person, who himself should be trustworthy. This most often applies to large and complex macros.

It is up to the validating person symbolgen option sas macros judge whether the output quality is sufficient. After several tests, if a variable does not appear to exist in the dataset the ErrCount macro variable at the calling level has to be increased by Other default values are very much symbolgen option sas macros dependent. Such quality may reduce validation time, increase chances on a positive outcome of the validation process and last but not least increase user-friendliness. Verify logic of default values of parameters of arguments, if any 5.

This kind of nested macros should not be used if possible, but can not always be avoided. This looks similar to declaring symbolgen option sas macros used variables which is obliged in several programming languages. An example is an alternative for a complex macro variable which value is conditionally dependent on several situations, macro CompBloc:. Verify that all macro created temporary SAS variables in temporary datasets have unique names stored as macro values
