TAB EXPAND

TAB EXPAND (SET)

Set Subcommand

Specify how tab characters are handled on Dataplot command lines.

By default, when Dataplot parses a command line it converts all non-printing characters, including tabs, to a single space character.

This command allows you to specify how tabs are to be handled. You can specify that the tab character be left as is or that it be replaced by one to 20 space characters.

This command is most likely to be useful when processing tabs contained within strings.

SET TAB EXPAND <ival>
where <ival> is a number or parameter in the range 0 to 20.

If <ival> is 0, then the tab character is left as is. If <ival> is a positive integer, then the tab character is replaced with <ival> spaces. If <ival> is greater than 20, it will be set to 20. Common choices for <ival> would be 3 or 5.

SET TAB EXPAND 0
SET TAB EXPAND 5

Tabs are replaced with a single space character.
