LOOKUP expressions for PBASIC is not available in LOOKUP for SX/B ?

T&E Engineer

I have a working PBASIC Lookup command:

LOOKUP char,[noparse][[/noparse]Char_B,Char_S,Char_2,Char_Space],eeAddr1

and the Char_B (and other expressions(?)) references a DATA statement

:
:
Char_B···DATA·· %00000000
··········· DATA·· %00000000
··········· DATA·· %01111111····· ' xxxxxxx
··········· DATA·· %01001001····· ' x..x..x
··········· DATA·· %01001001····· ' x..x..x
··········· DATA·· %01001001····· ' x..x..x
··········· DATA·· %00110110····· ' .xx.xx.
··········· DATA·· %00000000
··········· DATA·· 0

Is it possible to convert this PBASIC LOOKUP statement into a SX/B LOOKUP statement (or will an elaborate routine need to be written)?


SX/B statement....

LOOKUP char,Char_B,Char_S,Char_2,Char_Space,eeAddr2

:
:
Char_B:····
··········· DATA·· %00000000
··········· DATA·· %00000000
··········· DATA·· %01111111····· ' xxxxxxx
··········· DATA·· %01001001····· ' x..x..x
··········· DATA·· %01001001····· ' x..x..x
··········· DATA·· %01001001····· ' x..x..x
··········· DATA·· %00110110····· ' .xx.xx.
··········· DATA·· %00000000
··········· DATA·· 0

I get an error....INVALID PARAMETER "Char_B"

Bean? Somebody?

Thanks.

You'll need to do something like:

DEVICE          SX28, OSC4MHZ, TURBO, STACKX, OPTIONX
FREQ            4_000_000
 
char    VAR Byte
eeAddr2 VAR Word
temp    VAR Byte
bitMap  VAR Byte
 
PROGRAM Start
 
Start:
  char = 1
 
  IF char = 0 THEN
    eeAddr2 = Char_B
  ELSEIF char = 1 THEN
    eeAddr2 = Char_S
  ELSEIF char = 2 THEN
    eeAddr2 = Char_2
  ELSEIF char = 3 THEN
    eeAddr2 = Char_Space
  ENDIF
 
  FOR temp = 0 TO 7
    READINC eeAddr2, bitMap
  NEXT
 
END
 
Char_B:
  DATA 0
 
Char_S:
  DATA 1
 
Char_2:
  DATA 2
 
Char_Space:
  DATA 3
