- The P-STAT sort command can sort any mixture of numeric and
character data in ascending or descending order. Up to 15 fields
may be used to control the sort.
- Ties are maintained in the order in which they are found. Thus
a file can be resorted if more than 15 key fields are needed. If
the file is already in sort order on one or more major key
variables, the file can be sorted on a secondary variables within
the original sort structure.
- The LOOKUP command is used to add data in one or more tables
files to an input file. The files do not need to be in
sort order. Matching is done by comparing the values of common
- When there are many tables files the linking may be indirect.
This means that all the files do not need to have the same key
variables. Given three files with these variables
Input File First Table File Second Table File
Social Social Account Account
Security Q1 Q2 Security Number Q3 Number Q4
- Variable Social.Security provides a direct link between the
input file and the first table file. Variable Account.Number
provides a direct link between the first table file and the second
table file. Thus there is an indirect link between the input file
and the second table file. The resulting output file would have the
Security Q1 Q2 Number Q3 Q4
- The CONCAT command is used to join one or more files by adding
the cases. Various optional identifiers specify the variables that
are to be included in the output file.
A template can be provided to specify which variables are to be
included and their order in the output file. When no options are
specified, all variables in all of the input files are
placed in the output file.
