I'm trying to work out the number of seconds it takes for a macro to run.
I set two variables - time_start = ticks()
time_end = ticks()
To work out the total time in seconds I want to take away time_start from time_end (and divide by 60) but it gives an error.
Is this because they are strings?
If so, can they be converted to floats for the calculation? In a previous life, the ME10 macro language had a "val" function that would convert a string to a value (float I presume). Is there a way round it in IML?
I've answered my own question (I won't collect the points!)
If I declare the variables (including the result variable) as floats rather than strings, it seems to do the working out.
