String tokens and associated string

i adding function mrmp periodically poll new records bridge controller , send email selected records using xport.

i send... ig1v#rg1vr2,970,48#

a typical record reply this...
r1gvr,970,48,5,77,0,0,1239762623,65#


using limited ram , string functions in stdlib.h trying parse string , associate tokens (77) expanded strings mean reader of email message.

for example, token "77" (ascii 's') means "stopped"

so trying various methods create function takes token , returns address of associated string.

i have spent many hours googlng examples, success.

is there better, smaller more efficient way accomplish this?
i pass address of array[] , walk index. far haven't solved syntax.

code: [select]


#include <stdlib.h>      

char stdata[64] = "970,0,5,97,1,2,-1234567890,151";  // testing

// token $ expanded string null token $ expanded string null token $ expanded string null
char* stcontrollertokens[] = {
 "2", "s$slave", "g$garage\0b$house", "p$pond"};
char* stalarmtokens[] = {
 "7", "a$triggered", "h$horn sounding", "s$stopped", "o$delay entry", "i$instant", "m$maintenance", "c$close"};
char* stalarmlooptokens[] = {
 "7", "2$instant-windows", "3$always-glass", "4$delay-door", "5$interior", "6$button-press", "7$motion" "11$set", "15$heat-fire\0"};
char stunknown[] = "unknown";


char *parmadd=0;      // parameter address pointer
char *nextparmadd=0;  // next parameter address
long parameterlond=0;
int chksum=0; // checksum last parameter


/* sources 2 dimentional array of strings.
format...
token$expanded string\0      token$expanded string\0        token$expanded string\0

token 1 or more characters ending '$' following null terminated expanded string.
parmadd address of expanded string.
*/

char* findstralarmloop(const char *find)   // pointer address, parameter string delimiter
{
 int e;

 e = atoi(stalarmtokens[0]);  // 0th element holds number of tokens

 for (int = 1; <= e; i++)
 {
   parmadd=(strstr(stalarmtokens[i],find));
if(parmadd)
{
 return parmadd+strlen(find);
 
}
 
 }
}


void setup()  
{
 serial.begin(9600);
}


void loop()                    
{


 serial.print(findstralarmloop("s$"));
 delay(200);
}
