#### 20.4.1.4 Understanding how browse macros employ macro variables

The definition of each browse macro includes predefined macro variables for a destination for the link and for a label. Table 20-3 shows the default values of the link destination and link label used in <$_prev> and <$_next> for each file position.

Table 20-3 Default destination and label values for browse macros

Macro | File position in sequence | Destination value | Label value
<$_prev> | First file split from first FrameMaker file in sequence | None (no destination code) | At Start
First file split from: - each non-first FrameMaker file - all non-first unsplit files | <$$_seqprevfile> | <$$_seqprevtitle>
All other split files | <$$_prevfile> | <$$_prevtitle>
<$_next> | Last file split from last FrameMaker file in sequence | None (no destination code) | At End
Last file split from: - each non-last FrameMaker file - all non-last unsplit files | <$$_seqnextfile> | <$$_seqnexttitle>
All other split files | <$$_nextfile> | <$$_nexttitle>

Table 20-4 shows the meanings of the macro variables used in browse-macro definitions.

Table 20-4 Component macro variables for browse macros

Macro | Macro variable | Description
<$_prev> | <$$_seqprevfile> | Name of preceding file in sequence, with extension .htm
<$$_seqprevtitle> | Title listed in sequence for preceding FrameMaker file
<$$_prevfile> | File name of preceding split file
<$$_prevtitle> | Title of preceding split file
<$_next> | <$$_seqnextfile> | Name of following file in sequence, with extension .htm
<$$_seqnexttitle> | Title listed in sequence for following FrameMaker file
<$$_nextfile> | File name of following split file
<$$_nexttitle> | Title of following split file
Either macro | <$$_seqcurrfile> | Name of current file in sequence, with extension .htm
<$$_seqcurrtitle> | Title listed in sequence for current FrameMaker file
<$$_currfile> | File name of current split file
<$$_currtitle> | Title of current split file (the one used in HTML <title> element)

See §18.6 Referencing split and extract files for additional macro variables that refer to file names and titles of split and extracted files.
