Hi All,

I'm new here and have been reading thru this forum in the past week, so now
its time to ask/help where i can :-)

My 1st question is about PICbasic Pro (i have v2.33) , and its use of
setting a VAR as either a BIT, BYTE or WORD....
It wasn't too obvious in the manual, but does WORD refer to a 16 bit
value????

I had seen some posts about combining/seperating a VAR into 2 bytes and
back, and the answer given was about assigning a 'WORD' as a variable.

Lets assume the following:
(using an '877) i have assigned these variables:
lsbport var portC    'assigned the whole 8bit port C as "lsbport"
msbport" var portD    'assigned the whole 8bit port D as "msbport"


So, could i then use the following code to combine my 2 ports as a 16 bit
variable???
16bitport var word    'my variable which i'll use as a virtual 16 bit port.
lsbport    var    word.byte0    'assigns port C as lower 1/2 (lsb) of the
variable "16bitport"
msbport    var    word.byte1    ''assigns port D as upper 1/2 (msb) of the
variable "16bitport"

Essentially what i need to do is control upto 16 pins SIMULTANEOUSLY, by
writing/reading my variable called "16bitport".

Also note, if i only required to control say 10 pins, would i simply assign
2 ports as above (1 port being only 2 bits though), then combine/treat them
as a word, even though the leftover 6 bits of  the variable "16bitport"
wouldn't be accessable???
(in this case i would call the 'word' variable "10bitport" :-)


Am i going about this the right way? or have i totally lost the plot with
the term "word" ??? :-)

Thanx in advance everyone :-)
Marty Winch
