{title:Description}

{pstd}
Validates names of Stata variables that can be used to represent a network of size {it:nodes}. Stata variables 
are generated by combining {bf:stub()} with a consecutive number. If these Stata variables already exists, the 
command comes up with a new suggestion for naming variables. This command is mostly used for progamming.
