Run a block of code within a SWITCH()

Hi, 

All the examples of a switch include a very simple structure... 

For example:

= SWITCH([Month], 1, "January", 2, "February", 3, "March", 4, "April" , 5, "May", 6, "June", 7, "July", 8, "August" , 9, "September", 10, "October", 11, "November", 12, "December" , "Unknown month number" )

I have two blocks of code, and I only want to run one, depending on a condition. How do I run a BLOCK of code within a SWITCH()?

MEASURE_NAME =

SWITCH(

TRUE(),

SELECTEDVALUE(grouping[group]) = "all",

var total = CALCULATE(sum(data[value]), FILTER(data, [sex] <> "Persons" && ALL(grouping)))

var females = calculate(sum(data[value]), FILTER(data, [sex] = "Female" && ALL(grouping)))

,

SELECTEDVALUE(grouping[group]) <> "all",

var total = CALCULATE(sum(data[value]), FILTER(data, [sex] <> "Persons" ))

var females = calculate(sum(data[value]), FILTER(data, [sex] = "Female"))

)

RETURN

format(DIVIDE(females, total), "0.0%")

It seems to complain about the ',' in between the blocks, indicating to me that it struggles to evaluate multiple rows when the condition in the switch is true. I tried to put the blocks (in bold) in (  ) but that does not help.

Any suggestions?
