The >DATA command specifies the type of the input data (either ASCII or EBCDIC) and the basic collating sequence to be used in the particular SORT/XL (or MERGE/XL) operation. The collating sequence may be altered, if desired, by using the >ALTSEQ command. SYNTAX | |
>DATA [IS] {A[SCII] } [ , ] SEQ[UENCE] [IS] {A[SCII }
{E[BCDIC]} {E[BCDIC]}
|
DISCUSSION | |
The >DATA command must precede the first >ALTSEQ command found in any SORT/XL or MERGE/XL operation since it is the command that initiates the translation table. If the system encounters an >ALTSEQ command before a >DATA command, the message, THE DATA COMMAND MUST BE ISSUED BEFORE THE ALTSEQ OR SHOW COMMANDS, is displayed. If the >DATA command is entered again, following an >ALTSEQ command, the translation table (and the collating sequence) are reset to their original status. When you specify a particular sequence, it is for collating purposes only. A user-defined sequence can be designated only if the input data is ASCII. The input data is unchanged and appears in the output in its original form. In the example below, the >DATA command nullifies the effect of the >ALTSEQ command issued previously during a SORT/XL operation. EXAMPLES | |
The following example shows what occurs if you do not enter the >DATA command before an >ALTSEQ command. It also shows how the >DATA command nullifies the effect of the >ALTSEQ command issued previously during a SORT/XL operation.
