Stuck on CHAR arrays again

fogled@mizzou

Thanks so much to everyone that helped me out on my earlier post about CHAR arrays (http://www.amxforums.com/showthread.php?t=2205). I thought I had this more or less figured out, but now I've run into something else that doesn't quite make sense...

For a 16 output Autopatch switch, I've defined a variable CHAR vsw_out[30]. I figured 30 characters should be plenty to account for a handful of active outputs and the spaces that go between them when you actually send the command to the switch (I've actually only used 7 character positions so far). I've got all my ports mapped in DEFINE CONSTANT like projector1 = 5, polycom = 6, etc. I'm also using ELO touchpanels, and those ports are defined as tp1 = 1, tp2 = 2, etc. My touchpanel design 4 video previews that show up on the ELO, and any one of them can be selected as "active". I've got a selection variable for that (active_port), and an array that maps the selection variable to a port (port_map[] = {1,2,3,4}).

Almost everywhere I assign vsw_out to something - usually several ports like:

vsw_out = "itoa(projector1),' ',itoa(tp1),' ',itoa(polycom)"

... or a single port via the active panel array like:

vsw_out = "itoa(port_map[active_port])"

... I get no compile errors - everything seems fine.

But now I've just created another assignment for just the single projector port, like this:

vsw_out = "itoa(projector1)"

... and I keep getting a compile "ERROR: Illegal assignement statement" message. I don't understand why the itoa(projector1) doesn't give an error when it's combined with other stuff as in the first code snippet, and a different single-port assignment also doesn't give an errror as in the 2nd code snippet, but I am getting an error in the 3rd code snippet.

Please, can someone tell me what foolish Newbie mistake I'm making this time?

Thanks,

This compiles fine for me:

program_name='xxx'

define_constant

integer i = 1

define_variable

char s[10]

define_start

s = "itoa(i)"

Yeah, I think I must have a mistake like an errant " somewhere else in my code, and it's just provoking the error on that line. Thanks for the confirmation that it should compile OK.

Check the lines prior, sometimes the compiler error messages are off a line or two. What I generally do if there is any question exactly where the error is is to comment out the whole block, then start uncommenting sections to narrow it down.

Thanks Dave! It was the line above - very similar but I forgot the "itoa()" wrapper on that one. Now I'm wondering why I didn't define all those port maps as CHAR to begin with...
