FT_FSELECT()
Select a text file workarea
------------------------------------------------------------------------------
Syntax
FT_FSELECT( [ <nArea> ] ) -> nArea
Arguments
<nArea> is the text file workarea to select.
Returns
The current selected text file area.
Description
This function selects a text file "workarea" from 1 to 10. A
file may or may not be open in the selected area.
Passing 0 for <nArea> selects the next available workarea, similar
to Clipper's SELECT 0 command.
Each file is opened in its own "workarea", similar to the concept
used by dbf files. As provided, a maximum of 10 files (in 10
workareas) can be opened (assuming there are sufficient file
handles available). That number may be increased by modifying
the #define TEXT_WORKAREAS in the C source code and recompiling.
All the FT_F*() file functions operate on the file in the currently
selected text file workarea.
Text file workareas are separate from and independent of Clipper's
database workareas.
Examples
FT_FSELECT(1)
nFile1 := FT_FUSE( "temp.c" )
? FT_FLASTRE() // no. of lines in temp.c
FT_FSELECT(2)
nFile2 := FT_FUSE( "temp.h" )
? FT_FLASTRE() // no. of lines in temp.h
