Putting strings in Vars

Archiver · 2002-06-29 16:01

Hi All,

Simple question I am sure, but I can't seem to find the answer. How do I store a
string in a VAR?

myVar VAR Word
myVar = "My String"

This results in "Error, expected ":" or end of line". I can work around this
with SEROUT commands, as the strings are displayed on an LCD, but it is clumsy
and uses more lines. I know there has to be a way to do it!

Thanks,

Jonathan Peakall

You write

serstring var byte(4)

This gives you a variable with four bytes. Only bytes, not word, bit or nib.

There is no String type in PBASIC. What you can do is store strings in DATA
statements, like this:

Msg1 DATA "I love BASIC Stamps!", 0
Msg2 DATA "BASIC Stamps rule!", 0

Important: Notice that each string is terminated with a 0 (zero).

Then you can dump them to your display with a simple subroutine. Before you
call this subroutine, you must set the first character address in the
variable called eeAddr. This is as easy as

eeAddr = Msg1

...when using DATA statements as above. Here's the code that prints it:

Print_String:
READ eeAddr, char ' get a character
IF (char = 0) THEN Print_Done ' if zero, we're done
DEBUG char ' print the character
eeAddr = eeAddr + 1 ' point to next
GOTO Print_String

Print_Done:
RETURN

I hope this helps you.

I just found a good solution to a problem I had similar to this. My program
displayed a lot of text on an LCD as the user scrolled through the menus.
This was taking up a lot of my programming space. I know all of this can be
offloaded to an external eeprom but the pointer and memory locations always
get me confused and then the hassle of recalling the data through some sort
of counter. I just bought an lcd from scott edwards(TRM-425L), that can
store 90 pages of text for you. All you do is program in the text and give
it a number between 0 and 90. Then when you want the whole page of text a
simple command with the number of where it resides brings up the whole page.
This along with a keypad decoder makes a nifty little device. A bit pricey
but worth it.

Dear Jon;

What stamp does your 'string' code supposed to work on, it doesn't work
on my BASIC STAMP 2 ???? Gives errors ?? What's up ???

You must be doing something wrong ... I just pasted that routine into my
Stamp editor and it works fine on a stock BS2. Remember, I didn't supply a
whole program, just the working parts. You have to define the variables used
by the subroutine and then actually call it with GOSUB.

I guess I pasted what you posted hoping it would work. I didn't paste
the whole program, but then I did not have the whole program to paste.
Sorry about the error..
