Help with Inspect _src_ replacing all [SPACE]ALPHANUMERIC[SPACE] by space

Hello, I am wondering if anyone knows wether there is a Cobol symbol
representation where it can be used in the

INSPECT src_var REPLACING all " ALPHANUMERIC " by " "

I need to replace a space followed by any A-Z or 1-0 followed by
another space by just a space within a string. I thought perhaps there
is a symbol in cobol to represent all alphanumeric characters, where
say '*' was it, something like " '*' " , does anyone know if this is
possible?

Thanks
