Macro A calling Macro B?

[dheck2]

I would like to create a Driver Macro, that encorporates a number of sub macros. I would like to pass parameter values to a submacro if necessary and return a variable from the sub macro if desired. Is this possible and if so, how. Simple example would be fine. Any parameter passing would also be desirable.

Thx, Dave

There are 2 things I use along this same idea. One is what you were describing, where MACRO_1 calls MACRO_A.

Code: Select all

Let>MACRO_1=%SCRIPT_DIR%\Macro_1.scp
Let>MACRO_A=%SCRIPT_DIR%\Macro_A.scp
   //(Macro_A could be defined in Macro_1)

Macro>MACRO_1 /NEXTMACRO=%MACRO_A% /DATA1=%Some_data% /DATA2=%more_data% 

/////////////////////////////////////////////////////////
In MACRO_1

//Call macro passed in from calling script
MACRO>NEXTMACRO /DATA=%DATA1% /MOREDATA=%DATA2%

But also, you can put multiple subroutines in a macro. I use the 1st passed parameter to identify the subroutine that is called in the first lines of the macro.

Code: Select all

Let>MACRO_1=%SCRIPT_DIR%\Macro_1.scp

Macro>MACRO_1 /SubToRun=%SubRoutine_1% /DATA1=%Some_data% /DATA2=%more_data% 

//////////////////////////////////////////////////////////
In MACRO_1

//Call Subroutine passed in from calling script
GoSub>SubToRun,DATA1,DATA2

SRT>Sub1
End>Sub1

SRT>SubToRun
...
End>SubToRun
etc.

And to return a value back from the sub macro set the MACRO_RESULT variable.
