> 34 Automating Mif2Go conversions > 34.4 Executing operating-system commands > 34.4.2 Including macros and variables in system commands
System commands can include the following:
[UserVars]
[MacroVariables]
Predefined macro variables other than those listed here do not work in system commands. Macro variable <$$_macroparam> can be used only within a macro; see §28.7 Passing a parameter to a macro.
You can use macro expressions in system commands: math and string manipulations, conditional expressions, loops, formatted output, and so forth; see §28.6 Using expressions in macros.
You can have Mif2Go prompt you for values of user variables that appear in system commands; see §34.5 Supplying run-time values for user variables.
