value to string

[Googfan]

How do i convert a value to a string in pbasic 2.5

ie:
··· 1·· ·to "1"
··· 258 to "258"

i would like to display it on an lcd by modifying·my·"Sin to LCD"·code:


' {$STAMP BS2}
' {$PBASIC 2.5}

LineChars··· CON 16' === Number of Characters per Line
'----------------------------------------------
DEBUG "Ready..."
LcdHome····· CON $02 ' move cursor home
LcdCrsrL···· CON $10 ' move cursor left
LcdCrsrR···· CON $14 ' move cursor right
LcdDispL···· CON $18 ' shift chars left
LcdDispR···· CON $1C ' shift chars right
ochar······· VAR Byte
crsrPos····· VAR Byte
char········ VAR Byte
lcdone······ VAR Bit
LcdDirs····· VAR DIRB'.................dirs FOr I/O redirection
LcdBusOut··· VAR OUTB
LcdBusIn···· VAR INB
E··· PIN 1'....Adam Munich is· My PuppetmasterAdam Munich is· My Puppetmaster........................LCD Enable (1 = enabled)

to be more specific i want to display distance measured by a PING))) on the lcd

Look in the Basic Manual in the section on the DIG operator. This takes a value on the left and a digit position (power of ten) on the right and returns the value of the digit there. Add "0" to that and you have a displayable character.

(4352 DIG 0) + "0" is "2"
(4352 DIG 2) + "0" is "3"
(4352 DIG 4) + "0" is "0"

[Googfan]

no that takes it literal. I want to convert that '2' into ACSII Character "2"

That's what it does. Read the manual. Try it.

No DIG gives you the value of the digit not the character code. This seems to do what i want but its slow and memory hogging.

char VAR Byte
numb VAR Nib

numb = 563 DIG 2
GOSUB poo
DEBUG char
numb = 563 DIG 1
GOSUB poo
DEBUG char
numb = 563 DIG 0
GOSUB poo
DEBUG char
END

poo:
IF numb = 0 THEN char = $30
IF numb = 1 THEN char = $31
IF numb = 2 THEN char = $32
IF numb = 3 THEN char = $33
IF numb = 4 THEN char = $34
IF numb = 5 THEN char = $35
IF numb = 6 THEN char = $36
IF numb = 7 THEN char = $37
IF numb = 8 THEN char = $38
IF numb = 9 THEN char = $39
RETURN
