- Wed Nov 04, 2015 6:17 pm #33076 your code extract eer form eerfh20
I want to extract 20 to change refresh count, I thru the e's in to test instr, I keep getting 0 not 2/3

Why the end after the code ??

using rfh without quotes , how would you use a var then ??

- Wed Nov 04, 2015 6:29 pm #33077 using the quotes is proper form. Right ow the interpreter assumes if variable name has not been used yet that it is a string.

The below code also works.

Code: Select allmycommand = "eerfh20"
x = instr(mycommand,"rfh")
z = x + 3
y = mid(mycommand,x,z)
SERIALPRINTLN mycommand
SERIALPRINTLN x
serialprintln y
end
