It seems that the ANTNUM procedure in VLBAUTIL is changing the value of the INVERS adverb. This is not mentioned in the documentation, so I assume it is a bug. This occurs both in 31DEC15 and previously in at least 31DEC11.

Example:
>invers 2
>print invers
AIPS 1:      2
>print antnum('sc')
AIPS 1:     10
>print invers
AIPS 1:      1
