The TRANTAB Procedure

Example 4: Editing by Using a Quoted Character for Starting Position

Procedure features:

LIST statement

LOAD statement

REPLACE statement

SAVE statement

This example creates a new translation table by editing the already fixed ASCII translation table. The first occurrence of the hexadecimal equivalent of the quoted character that was specified in the REPLACE statement is the starting position for the changes to the table. This method differs from Editing by Specifying a Decimal Value for Starting Position in that you do not need to know the exact position at which to start the changes to the table. PROC TRANTAB finds the correct position for you.

The edited table is saved under a new name. Horizontal arrows in both SAS logs denote the edited rows in the translation table.
