Under normal circumstances the blank character is a space (character 32). However, under certain circumstances you may want or need to redefine that. For example, if you have a file to be exported that uses the space as a delimiter you may want to set your DELIMIT character to the space. In this case, you will need to set your blank to some other character. The example below shows how this might work.

SET BLANK='@'
SET@DELIMIT=' '
 
Body of command file
 
SET@DELIMIT=','
SET@BLANK=' '

Notice that each command after the SET BLANK command uses that character instead of the space.
