Hi experts ,
i am using Keil uversion3. I wrote the program in c , but when compiling this programme it gave me these messages:

compiling pwm.c...
pwm.c(1): warning C318: can't open file 'regex.h'
PWM.C(3): error C129: missing ';' before 'pwm'
pwm.c - 1 Error(s), 1 Warning(s).

please tell me what to do and thank in advance
 

is the file 'regex.h'in the same folder as c file, if nt try tat i guess.
for other problem post the code here there is syntax error sumwhere perhaps.

Than you partzz for regarding my problem
the file 'regex.h' in the same folder as c, and here is the c prog
#include <regex.h>
#include <stdio.h>
viod pwm (unsigned char);
viod main
{
p2=0x00;
while(1)
{
unsigned char msec;
unsigned char nsec;
msec=100;
nsec=100-msec;
p2-0x01;
pwm(msec);
p2=0x00;
pwm(nsec);
}
}
void pwm(unsigned char ms)
{
unsigned int i;
for(i=0;i<ms<i++)
{
TMOD=0x01;
TH0=0xFC;
TL0=0x67;
TR0=0x01;
while(TF0==0x00);
TR0=0x00;
TF0=0x00;
}
}
 

If the header is in the same folder then use #include "regex.h" instead of #include <regex.h>
 

Code: 
viod pwm (unsigned char);
viod main

u hav written viod instead of void.
also post your code b/w # sign on top of your edit window

i hav microvision 4 and i hav my file in same folder as c and by compiler accepts both <font.h> and "font.h".is microvision 3 diff?
 

I don't have uvision3 but in uvision 4 it doesn't work (I just tried it) and this it the case with a few compilers I have worked with , <> searches in the predefined system path while "" searches in the same folder
 

I dont know what the hell you wrote..

Code: 
[COLOR=#FF0000]#include <reg52.h>[/COLOR]
#include <stdio.h>
[COLOR=#FF0000]#define pw P2[/COLOR]
void pwm(unsigned char ms);
[COLOR=#008000]void main()[/COLOR]
{
[COLOR=#008000]pw=0x00;[/COLOR]
while(1)
 {
  unsigned char msec;
  unsigned char nsec;
  msec=100;
  nsec=100-msec;
[COLOR=#FF0000]  pw=0x01;[/COLOR]
  pwm(msec); 
  pw=0x00;
  pwm(nsec);
 }
}
void pwm(unsigned char ms)
{
 unsigned int i;
 for(i=0;i<ms<i++)
 {
   TMOD=0x01;
   TH0=0xFC;
   TL0=0x67;
   TR0=0x01;
   while(TF0==0x00);
   TR0=0x00;
   TF0=0x00;
 }
}
Try this..
