Eric,
Here is what the code looks like right now:
program snchygrometer
%%#include <ctype.h>
%%#include <stdlib.h>
%%#include <stdio.h>
%%char rob[10] ;
char *roba;
assign roba to "rawdata" ;
monitor roba ;
float ch1 ;
float ch2 ;
float ch3 ;
float ch4 ;
float ch5 ;
assign ch1 to "PV1";
assign ch2 to "PV2";
assign ch3 to "PV3";
assign ch4 to "PV4";
assign ch5 to "PV5";
%%int v ;
%%int z ;
%%extern char *wa1 ;
%%char *sign="+-" ;
%{
when()
{
rob=&roba; /*i dont know how to do this & wont work w/ roba as just
rob*/
v=rob[0]; /*Get first char from string*/
wa1=strpbrk(rob, "+-"); /*Break string at +-,rest is wa1*/
z=(float)wa1; /*convert string to float z*/
ss ss1 {
state state1 {
when ( v==1) {
ch1 = z; pvPut(ch1);
} state state2
}
state state2 {
when ( v==2) {
ch2 = z; pvPut(ch2);
} state state3
}
state state3 {
when ( v==3) {
ch3 = z; pvPut(ch3);
} state state4
}
state state4 {
when ( v==4) {
ch4 = z; pvPut(ch4);
} state state5
}
state state5 {
when ( v==5) {
ch5 = z; pvPut(ch5);
} state state1
}
}
(This is the entire code).
and here is the error we are getting:

What we are wondering is, why does it think rob is defaulting to int,
when we are setting it as char?? Obviously, there is something wrong
with array vs pointer (this is what I have been telling to my
students), but this seems to compile without any issues outside of
EPICS (well, the original ones we started out did, anyway).

I'm not sure what you have changed, but the code you posted
originally seems
to be mixing up the notion of "array of characters" and "pointer to
character". See my comment below:
program snchygrometer
%%#include <ctype.h>
%%#include <stdlib.h>
%%#include <stdio.h>
%%char rob[10] ;
char *roba;
assign roba to "rawdata" ;
monitor roba ;
float ch1 ;
float ch2 ;
float ch3 ;
float ch4 ;
float ch5 ;
assign ch1 to "PV1";
assign ch2 to "PV2";
assign ch3 to "PV3";
assign ch4 to "PV4";
assign ch5 to "PV5";
int v ;
float z ;
%%extern char *wa1 ;
%%char *sign="+-" ;
%{
rob=&roba <<<<<<<<<<<<< EVEN WITH A SEMICOLON AT
THE END
THIS LINE MAKES NO SENSE.
v=rob[0]; /*Get first char from string*/
wa1=strpbrk(rob, "+-"); /*Break string at +-,rest is wa1*/
z=(float)wa1; /*convert string to float z*/
}%
Perhaps you could mail me your latest code??
