Please help take alook at my attchment i got many error which i could not solved

hummm no error here when compiling your code. Looks like your PBP .INC, .BAS files are corrupted...

Reinstall your PBP and MPLAB an tell us what's happening.

i am using microcode studio suite a free software and picbasic pro 2.3 i only unzipped the pbp to drive c of my pc

[mister_e]

Reason is simple now. Version 2.3 don't support OWIN and OWOUT.. must buy an upgrade disk.

$55 - match ROM
$10,$BB,$40,$2C,$00,$08,$00,$F9 - 64 bit rom code for sensor 1
$44 - do temp conversion

sensor 1:
OWOUT PortB.0, 1, [$55,$10,$BB,$40,$2C,$00,$08,$00,$F9,$44]
' match ROM &
pause 1000 ' conversion time 750 ms
OWOUT PortB.0, 1, [$55,$10,$BB,$40,$2C,$00,$08,$00,$F9,$BE]
' match ROM & read scratchpad memory

OWIN PortB.0, 2, [R_Temp0.Lowbyte, R_Temp0.Highbyte,skip4,count_remain_0,count_per_c_ 0]

same for sensor 2,3,4 --- if you heave enough space in PIC16F84
