 Please give me your opinion. My plan is not yet the concrete,
but a few of my new plan are:
1. Improvement of function of an HTML output.
  exec_sql -H -O "<TABLE option>"           -O "*:<TH option1>" -O "name:<TH option2>"           -O "*:<TD option3>" -O
"addr:<TDoption4>"           -F "name:<font color='0000ff' size=4>%-7.7s</font>"           -F "addr:<fonr
color='ff0000'>%s</font>"          "select * from test where ..."
 
2. Snapshot cursor operation.    exec_sql -c cur "select * from test where ..."  exec_sql "open cur"  exec_sql "fetch
incur into :r1, :r2"  echo "r1=$r1  r2=$r2"  exec_sql "close cur"  # Declare cursor operation is already implemented.

 I think that it is necessary, because in the inside of the 
double quotes, it can be used $variable and it is possible to
describe the SQL statement in the multiple line.  
 ex) exec_sql "select * from test        where name='$DATA' and              addr='$ADATA'"

 I use alias too, but I do not know the method for aliasing 
double quotes.  ex) alias E='exec_sql'
 (Shell program) ----------------------------------------------------- #!/usr/local/bin/bash  function E {  exec_sql
"$@"} ----------------------------------------------------- (KUBO Takehiro taught me this method.)
