you can use stored macro as Dietrich suggested, but then you have to
point out where the library can be found:
Then you have to compile your macros:
%macro test / store;
In order to use the autocall library there are 2 restrictions:
1 you can only use macros which are compiled on startup. New and
altered macros will not get in effect until the next startup.
2 the name of the macro must be the same as the name of the file which
contains the macro code.
Furthermore as you stated, the autocall library must be concatenated to
the existing autocall libraries at startup, f.i. in the autoexec file.
The files you listed contain the source code of the standard SAS
autocall macros. You could try to alter your autoexec in the way that
you do not concatenate your autocall library but instead replace the
existing with yours. You will not be able to use the standard autocall
