Compiler error when declaring array using constant

Brian Szuter

The following code generates a this error when compiled:

C51 COMPILER V6.02 - SN: XXXXX-XXXXX
COPYRIGHT KEIL ELEKTRONIK GmbH 1987 - 1999
*** ERROR C221 IN LINE 7 OF QUEUE_I.H: non-constant case/dim expression

const unsigned char code BUF_SIZE = 40;

BYTE Qbuf[BUF_SIZE];

I get the same error whether or not I use "code". I've worked around this by using
#define BUF_SIZE 40
but this isn't optimal for style, and debugging purposes.

Has anyone else seen this problem?
