I included rtx51tny.h in the files, and tried to link them with BL51 as follows: bl51 module1.obj, module2.obj, module3.obj rtx51tiny However, the linker complains about the rtx51.lib file: MS-DOS BL51 BANKED LINKER/LOCATER V2.01 COPYRIGHT KEIL ELEKTRONIK GmbH 1987 - 1991 *** FATAL ERROR 210: I/O ERROR ON INPUT FILE: EXCEPTION 0021H: PATH OR FILE NOT FOUND FILE: C:\C51PROGR\LIB\RTX51.LIB Can anyone tell me what I'm missing? thanks for reading...
