I can send message normally using the following code

Code: 
HSerout ["AT+CMGS=",34,"+91##########",34,13] 
HSERIN 5000 , error, [WAIT(">")]	
HSEROUT[ "Message" ,10,13]
HSEROUT[ 26] 
HSERIN 3000 , Error,[WAIT("+CMG")]
LCDout "OK"

How can I send message to a number which is stored from location 0 to 9 in eeprom

I tried storing value in variable N1 TO N9 respectively

HSerout ["AT+CMGS=",34,#N1,#N2,#N3,#N4,#N5,#N6,#N7,#N8,#N9,34,13]

This causes the sim300 to hang...

You don't need to store the numbers in eeprom. Just store it in ROM memory and you can read it into RAM on startup before entering the super loop. It will be available all the time when PIC has power. Use a string variable or character array. in HSerialOut[] procedure call pass the variable (array) which holds the number.
 
Thanks for your suggestion... But my numbers are stored in eeprom only.... I can read them from eeprom into a variable and do... I tried sending the numbers one by one also in a loop but it does not work... sim 300 hangs... Pl suggest ... PICBASIC pro does not support string variable I think....
 

See the attached code. I tested it in Proteus and it works fine. I saw eeprom example code at PBP website and wrote this code. Try adding more numbers to eeprom.

Try this code. Before Compiling change the four 10 digit mobile numbers in eeprom[] instruction.

From where? After sending AT+CMGS="...?

It worked for me in Proteus. I have used PIC16F877A @ 4 MHz external clock. Change it to your MCU and clock.

Edit: Increase SerIn Timeout and delays and try.

It worked - .. thanks for your help.... I was using HSerout ["AT+CMGS=",34] instead of which I used HSerout ["AT+CMGS=",$22]
Thanks a lot
 

Decimal 34 and 0x22 are the same. It is ASCII char for double quotes. The versions with 34 and $22 both works for me.
 

But in mine it does not - 34 does not work and $22 works !! Even I am stumped...
