Description

The FCLOSE() function will close an open text file, writing the associated buffers to disk. The <expN> is the file pointer obtained from FCREATE() or FOPEN(). The file pointer must be assigned when the file is first opened using the FOPEN() or FCREATE() functions. If an error occurs during the operation -1 is returned by the FERROR() function.

Example

use accounts
scatter to flist
m_total=alen(flist)
fp=fcreate("new.txt")
if ferror()=-1
    dialog box "The file could not be created."
else
    for n=1 to m_total
        fwrite(m->fp,flist[n],80)
    next
endif
fclose(fp)
if ferror()=-1
    dialog box "The file could not be closed."
endif
