VAR array compile issue

Hi guys, thanks for help to date and ill try and return the favor as i learn more about the pic programming.

the following code will not compile when i use the variable T and loop , where if i expand the code out and assign a number in place of Varable T its very happy ,

It there away to do this without expanding out the code and not use fixed number in place of varable T

Regards

        '-------------- Low Address /High Address /Data / Inv Data bytes  --------------       
  For T = 1 to 4           
    FOR Index = 7 TO 0 step -1              ' Loop for 8 bits data start at bit 7-0 and send
      IF STDByte[T].0[Index] = 0 THEN        ' Get polarity of each data bit to send
        Space = Zero                        ' Pulse time = Burst (560us) + Zero (560us) = 1.12mS for a "0" data bit
      ELSE
        Space = One                          ' Pulse time = Burst (560us) + One (1680us) = 2.24mS for a "1" data bit
      ENDIF
   
      GPIO.0 = 0                            ' Set Output low
      pauseus Burst                        ' load the burst for 0.56ms     
      GPIO.0 = 1                            ' Set Output high
      pauseus space                        ' High for duration of either Zero or One value ,for each address/data b
      Total[T] = Total[T] + space + burst  ' store total time of string 
    NEXT Index                              ' Loop until 8 data-bits sent of DByte(X)
  Next T

Have a variable like

Code:

---

Temp VAR BYTE

---

Then swap the variables in your array.
Your new code will look like below.

Code:

---


        '-------------- Low Address /High Address /Data / Inv Data bytes  --------------       
  For T = 1 to 4           
   
    FOR Index = 7 TO 0 step -1              ' Loop for 8 bits data start at bit 7-0 and send
     
      temp = STDByte[T]
     
      IF temp.0[Index] = 0 THEN            ' Get polarity of each data bit to send
        Space = Zero                        ' Pulse time = Burst (560us) + Zero (560us) = 1.12mS for a "0" data bit
      ELSE
        Space = One                          ' Pulse time = Burst (560us) + One (1680us) = 2.24mS for a "1" data bit
      ENDIF

      STDByte[T] = temp
   
      GPIO.0 = 0                            ' Set Output low
      pauseus Burst                        ' load the burst for 0.56ms     
      GPIO.0 = 1                            ' Set Output high
      pauseus space                        ' High for duration of either Zero or One value ,for each address/data b
      Total[T] = Total[T] + space + burst  ' store total time of string 
    NEXT Index                              ' Loop until 8 data-bits sent of DByte(X)
   
  Next T

thanks Sayzar , but i tried that before i posted , and just then , still get bad expression error and syntax error , using picbasic pro 5.0.0.0 , pbpx 3.0.4.1

is there something i am missing ??

Cheers

sheldon


temp = STDByte[T] - bad expression error
STDByte[T] = temp - syntax error

i think i found the issue i forgot to define dbbyte var when i changed it over from dbyte1, cheers
