If i have this program:
__________________________________________________________________________-
program ProvaPassaggioVariabilr16F88
dim y as byte '<--- I don't want use this global Variable
' Declarations section
sub function funzione(dim x as byte) as byte ' DefineCircle function returns a byte value
result = x
end sub
main:
'dim y as byte <---- i want use the variable here as local(what about save memory pic) but compiler see me an error
' Main program
y = funzione(5)
nop
end.
__________________________________________________________________________
why? is required declare the variable as Global, and i can't use it as local where i need? it's ridicolous!!!
thank you.

Pass a variable using the function without having global var
Post your requests and ideas on the future development of mikroBasic PRO for PIC.

It isn't required to declare y as global. Optimizer probably removed this variable (and assignment) when declared as local because it wasn't used later on. For debugging, when you want optimizer to refrain from optimizing out a variable, use the volatile specifier, likeleo73 wrote:why? is required declare the variable as Global, and i can't use it as local where i need? it's ridicolous!!!
Code: Select all
main:
dim y as byte volatile
