The /CROSS_REFERENCE qualifier causes the compiler to generate a cross-reference listing. The format of the /CROSS_REFERENCE qualifier is as follows: /[NO]CROSS_REFERENCE[=[NO]KEYWORDS] The cross-reference listing shows program symbols, their class, and the program lines in which they are referenced. The /CROSS_REFERENCE=KEYWORDS qualifier specifies that the cross-reference listing includes all references to VSI BASIC keywords. /CROSS_REFERENCE is the same as /CROSS_REFERENCE = NOKEYWORDS. The /NOCROSS_REFERENCE qualifier suppresses the creation of a cross-reference listing. See the HP BASIC for OpenVMS Alpha and VAX Systems User Manual for more information on cross reference listings. The default is /NOCROSS_REFERENCE.
