Accessing parameters in a VAR block as longs

ciphernet

Hi all,

Get a bit of trouble getting this code to work... What am I doing wrong???

I defined a DAT block with LONG values (approx 300 longs) and I get a constant error message: "Size overwrite must be smaller"


(Motor and mot·are defined·as LONG vars in the var section of my SPIN program)

In SPIN:


Motor:=MOTOR_MODE_VALUES.LONG[noparse][[/noparse]mot]


DAT
MOTOR_MODE_VALUES

·LONG·· 0095,0195,0295
·LONG·· 0395,0495,0595
·LONG·· 0695,0795,0895
·etc..


What am I doing wrong???

MOTOR_MODE_VALUES is already LONG since that's the declaration you're using. I'm not sure why you're getting the message other than that you don't need it. Just use Motor := MOTOR_MODE_VALUES[noparse][[/noparse]mot]

Hi Mike,

I have tried that and I am checking the result on my Scopemeter. It seems like nothing happens, but I will have to check my code again. At least I get no error messages anymore.

Thanks for your reply. Your knowledge·about the prop is amazing.. :-)

Following code should work properly.

  Motor:=LONG[noparse][[/noparse]@MOTOR_MODE_VALUES][noparse][[/noparse]mot]

The code you was using implies that the variable is an array. But it is declared in DAT section, so you can only access it as address.
