ACS-SASSI generates a large amount of data that tends to be processed using repetitive tasks.

A Macro in ACS-SASSI is a specially formatted *.pre file that has variables. Variables are defiend by a positive integer number that is encapsulated with dollar signs (example $1$, $2$ … ,$10293$). Macros are loaded into the Submodler with the use of the LOADMACRO command. The user can then call the macro by using the MACRO Command. When the user calls the macro command the variables are replaced by the arguments given to the instruction. The integer in the variable is directly related to the argument number in the command.
