! WHILE Loop —The WHILE loop evaluates a relational expression and, if it is true, then the statement block is executed.
When the statement block has completed execution, the expression will be reevaluated again and, if it is true, the
statement block is executed again. This continues until the expression is false. Use the conditions specified in the IF
conditional to create the relational expression and the following syntax for the WHILE loop:
WHILE DO END
! WRITE Command —The WRITE command writes values to the screen. These values can be variables or constants of
type integer$, string$, date$, or time$. The write command is used in conjunction with either the IF conditional, WHILE
loop, or FOR loop.
DTCL Return Values
Understanding the values returned by the DTCL commands will make variables and script flow control more useful. Any
positive number returned from a DTCL command indicates the command was successful. A negative value indicates an error.
The following table includes all of the possible negative DTCL return values and a short description of the cause of the error.
NOTE: The exception to that rule is the connect and login command. If the connect command returns a positive
number, that number is the connection ID assigned to that connection. The login command may return one
of three positive values: 0 (no access granted), 1 (monitor access granted), or 2 (full access granted).
