Chapter 3 Alternate Collating Sequence Specifications Normally, XSORT uses the standard ASCII collating sequence included in appendix C. If you want to change the standard collating sequence, you must code an S in column 26 of the Header Specification and code a set of ALTSEQ specifications. You can code whatever number of ALTSEQ lines you need. Each of your statements must begin with ALTSEQ and contain no more than 80 column entries per line. Users accustomed to a 96 column line will have to convert their programs to the 80 column format. However, it is not necessary to fill in all 80 columns of one ALTSEQ line before continuing on to the next. As long as you enter the ALTSEQ in the first six columns, and submit your characters in pairs as described below, you can enter ALTSEQ characters without filling out all 80 column positions of a line. (The specification forms show only 72 columns but 80 columns per line are allowed.) If you specify an alternate collating sequence, you cannot use packed data for record selection factors or sort control fields. Do not enter a P in column 8 of your Record Type specifications or n column 8 of your Field Description specs used to define control fields.
