"Macro Madness"

ndoromal

Hi All-

I'm new to the RM community and this is my first forum post (so please go easy

I'm trying to do basic arithmetic with a macro; I want to assign a value to a macro and then decrement it by one. (The sad thing is that there is probably a better way to achieve the same end for the process, but I've invested so much time, at this point, I want to figure out how to do this.)

I've tried a number of approaches:

using eval(%{MACRO_NAME}) syntax
使用# {MACRO_NAME}语法

eval(%{MACRO_NAME}) - 1

eval(%{MACRO_NAME} -1)

using one macro (setting MACRO_NAME value and then setting MACRO_NAME to MACRO_NAME - 1

using two macros (setting MACRO_NAME value and then setting MACRO2 to MACRO_NAME - 1

using the Generate Macro operator

using the Set Macro operator

I'm having trouble attaching the process, so apologies for not posting it.

Thank you in advance for the help!

Hi Lionel-

Thank you so much! I was working on this late last night... I probably should have hit pause and resumed this morning. Your help is greatly appreciated!
