From the CSR,
"The TO convention must be used to specify the variable list. Thus, variables specified must be consecutive"
If the data meet this requirement, you would use two single-variable target lists to specify the first and last variables in the vector.
If this is not the case, you might be able to create a macro - directly or using the SPSSINC SELECT VARIABLES extension command depending on what you need to do with the vector.
