what is the problem with this 8051 code?

[Delphianrex]

hi
This code is for a Humidity Measurement circuit that i got from internet. but when i try to compile the source code with Keil C51, it gives a warning on 46th line and terminates the compilation process. but unfortunately i can't catch the problem. could anyone check the code and correct it????
The warning is on this function:

void lcd_dataa(unsigned char *disp)
{
unsigned char x;
for(x=0;disp[x]!=0;x++)
{
lcd_data(disp[x]);
}
}


Thanks in advance

There was a check box in the project options->Output tab->Create Hex file
This check box (create hex file) should be checked to make the output hex file.
More over it was a misinterpretation that there is a mistake with line 46. The error msg was L46 and i got that this wants to say "Line46". in fact this is the error code not the line number!
