Hi! I'm a newbie with using Keil C-51 Compiler! I want to compile a sourcecode and always recive Error 107 unbalanced #if-endif controls! I've looked to all statements and i can not find any mistakes! There is another one! Error 106 unclosed comment! In the compiler discribtion is written: it occurs if there is a '*/' missing, but i don't use comments like this /*--*/ only // comments! because if i am using this /*--*/ type the there is apearring another Error: like this error 141 in line ... near '/' please could anybody help me or give me an advise which is probably wrong! Thanks DANIEL
