{} in shell programming

Could someone please tell me what {} mean when they surround a variable?

For instance,

$FILE = 'basename $1' //what is passed into this script
$BANK = 'dirname $1'
$INFILE = ${FILE}.${BANK}.$$

What does $INFILE contain after this assignment?

Please let me know
Thanks
G

NAME
tbf2lps - convert a muCRL LPE to an mCRL2 LPS SYNOPSIS
tbf2lps [OPTION]... [INFILE [OUTFILE]] DESCRIPTION
Read mCRL LPS from INFILE, convert it to a mCRL2 LPS and save the result to OUTFILE. If OUTFILE is not present, stdout is used. If INFILE is not present, stdin is used. To use stdin and save the output to a file, use '-' for INFILE. This conversion assumes that Bool is the boolean sort with constructors T and F. Additionally, the following conversions on the data speci- fication will be applied: constructors T, F: -> Bool are replaced by true and false, mapping and: Bool # Bool -> Bool is replaced by ||, and mapping eq: S # S -> Bool is replaced by == for each sort S OPTIONS
OPTION can be any of the following: -n, --no-conv-map do not apply conversion of mappings and equations --timings[=FILE] append timing measurements to FILE. Measurements are written to standard error if no FILE is provided Standard options: -q, --quiet do not display warning messages -v, --verbose display short intermediate messages -d, --debug display detailed intermediate messages --log-level=LEVEL display intermediate messages up to and including level -h, --help display help information --version display version information AUTHOR
