Hi all,

I am using PLM51 software from intel to assemble my code but there is some
problem .

I program a source myfile1.asm and (in this file call a procedure "_distance"

and declare the procedure external "EXTRN DATA (_distance)" ), After

compiling this I get the myfile1.obj without any errors .Similarly I program

a file myfile2.asm and could compile it to myfile2.obj Succesfully with asm51.exe .

But when I try to link the two files together with the library my8051.lib

and give the command through my batchfile

: RL51.exe myfile1.obj,myfile2.obj,my8051.lib


the DOS screen display :

Warning 1 : UNRESOLVED EXTERNAL SYMBOL
SYMBOL: _DISTANCE
Module: MYFILE1.OBJ
REFERENCE: 0007H


Warning 2 : REFERENCE MADE TO UNRESOLVED EXTERNAL
SYMBOL: _DISTANCE
MODULE: MYFILE1.OBJ
REFERENCE: 001EH

I saw intel site but could not find any good documentation regarding asm51 and BL51.

any help most appreciated.


Thanks
Sanjeev
