XREF Syntax: XREF {d:} filename {$P} Explanation: XREF provides a cross-reference summary of variable usage in a program. XREF requires the .PRN and .SYM files produced by MAC or RMAC for input to the program. The SYM and PRN files must have the same filename as the filename in the XREF command tail. XREF outputs a file of type .XRF. Examples: A>XREF b:MYPROG A>XREF b:MYPROG $P HELP>
