ArrayRead on longer arrays

[amgen]

Hello,
I havn't found much info on arrayread, but
I would like to use arrayread on an array of about 1000. The maxlength max val is 256, and when I tried leaving off the maxlength, if the "wait" is not found, the routine runs-off-the-end and infact crashes out the program.

ParseSUB:        'InDX must be < 256
b6=0:B7=0  
arrayread rcvdata, INDX,NONE,  [wait("RUN")]:b6=1 
NONE:arrayread rcvdata, INDX,NONE1,  [wait("STOP")]:b7=1 
NONE1: RETURN

This works well if index < 256. Is there a way to do the same parse for longer arrays ?

I haven't tried anything yet, but perhaps you could break your 'rcvdata' into smaller arrays, like

hserin [STR rcvdata1 \255]:hserin [STR rcvdata2 \255]:hserin [STR rcvdata3 \255]

Then you can test all 3 arrays for RUN and STOP.

Charles,
You got me thinking about breaking up array, so I tried a few things,
Arrayread Array[index point in array], limit,goto................................. starts read at a point into array.

After storing chars with RXint, framing with start and end char to start loading and triggering a finish to rcv and parse, I have an index of char count. So now I can figure indexing points and lengths as follows.

 ParseSUB:        'InDX up to 500 dec
b6=0 
if indx<250 then             'char count less than 250 for 1 sweep 
arrayread rcvdata, INDX,NONE,  [wait("RUN")]:b6=1:return
else 
INDX1=indx-245                'char count >250 and < 500 about
arrayread rcvdata, 250,NONE1,  [wait("RUN")]:b6=1:return  'test first 250 char in array
NONE1;
arrayread rcvdata[245], INDX1,NONE,  [wait("RUN")]:b6=1:return  'test balance of chars  at >245 indx
NONE: RETURN                    'back-up a few chars incase "wait" straddles arrayread
endif

Same setup for other parses, I'm not sure if some code could be reduced.
