Coding question

Dose anyone know if <ctrl-E> <ctrl-E><x30><0d>, can be entered into code and work or does the AMX see the <ctrl-E> as an ENQ ?

Assuming that you are referring to NS2 compiling NetLinx code:

You can put anything you like in a CHAR.

There would be no purpose in putting such a character anywhere else in the code.

This code compiles fine:

PROGRAM_NAME='Sandpit'
define_variable
char a[100] 
define_start
a = "$05,$05,$30,$0D"

I note however that the following code does not compile, which appears to be a compiler bug:

PROGRAM_NAME='Sandpit'
define_variable
char a[100] = "$05,$05,$30,$0D"

I get "RHS is not a constant" when defining a variable with an initial value which is a string surrounded by double quotes. It compiles OK for a define_constant and the contents of the string have no bearing on it.

Can't do this, it's got to be:

char a[100] = {$05,$05,$30,$0D}

Accepting that is the rule, I observe that double quotes seem to work OK in every other comparable situation, which is a trap for young (and old) players.

Thanks for the info. I tried a <ctrl e> directly on the command line and it gives a 'ENQ' as the result for pressing these keys. I had already tried the 05,05,30,0d but was unable to get the expected result from the device. For now I just did it the old fashion way with a counter and do_push to toggle the device between its logic states.
