Call QUEL
The statement call quel calls the QUEL Terminal Monitor.
flags
Specifies the flags to be in effect. The value is a list of flags. Includes the following system level command line flags:
+a|-a
+d|-d
+s|-s
Separate items in the list with a blank or by pressing the Tab key.
Examples
Run QBF in the append mode, suppressing status messages, using the QBFName "expenses":
call qbf (qbfname = "expenses",
flags = "-mappend -s");
Run a default report on Emptable in the column mode:
call report (name = "emptable",
mode = "column");
Call report on a temporary table. The temporary table's name and contents are both based on user input. Note that in QUEL, embedded double quotes must always be dereferenced with a backslash (\), regardless of the operating system in use:
retrieve into :tbl (orders.all)
where qualification (status = status,
custno = custno);
call report (name = "orders",
param = "table=\"" + :tbl + "\"")
The following example illustrates how to pass different data types in a call report statement:
• Use the following Report-Writer query specification:
.QUERY retrieve (callreptable.all)
where callreptable.db_int = $rw_int
and callreptable.db_char = '$rw_char'
and callreptable.db_date = '$rw_date'
• Include the following 4GL code in your application:
initialize (h_param = c80 not null) =
begin
end
"Callrep" =
begin
/* Construct a parameter string by */
/* concatenating fields or variables with */
/* text constants. Data comes from fields */
/* "scr_int," "scr_char," and "scr_date," */
/* with data types INTEGER, CHAR, AND DATE, */
/* respectively. As they are concatenated, */
/* non-character fields are converted to */
/* character type using the function VARCHAR. */
h_param = "rw_int=" + varchar(:scr_int)
+ "rw_char=\"" + :scr_char + "\""
+ " rw_date=\""
+ varchar(:scr_date) + "\"";
call report (report = 'callrep',
param = :h_param);
end
