goto USE CASE
Witt,
A very nice construct that is far superior to GOTO is CASE. CASE also prevents dead ends and allows for many outcomes depending on the variable.
You can set it up to have infinite conditions, 256 max I believe, to perform various tasks depending on the input to the CASE statement.
Just define $VAR above from some action and CASE will do the rest!
case $VAR in
VAR1 ) Do some statement ;;
VAR2 ) Do different statement ;;
VAR3 ) Do another different statement;;
* ) Do default statement and exit from CASE ;;
esac

EXECUTE(7) SQL Commands EXECUTE(7) NAME
EXECUTE - execute a prepared statement SYNOPSIS
EXECUTE name [ ( parameter [, ...] ) ] DESCRIPTION
EXECUTE is used to execute a previously prepared statement. Since prepared statements only exist for the duration of a session, the pre- pared statement must have been created by a PREPARE statement executed earlier in the current session. If the PREPARE statement that created the statement specified some parameters, a compatible set of parameters must be passed to the EXECUTE statement, or else an error is raised. Note that (unlike functions) prepared statements are not overloaded based on the type or number of their parameters; the name of a prepared statement must be unique within a database session. For more information on the creation and usage of prepared statements, see PREPARE [prepare(7)]. PARAMETERS
name The name of the prepared statement to execute. parameter The actual value of a parameter to the prepared statement. This must be an expression yielding a value that is compatible with the data type of this parameter, as was determined when the prepared statement was created. OUTPUTS
The command tag returned by EXECUTE is that of the prepared statement, and not EXECUTE. EXAMPLES
Examples are given in the Examples [prepare(7)] section of the PREPARE [prepare(7)] documentation. COMPATIBILITY
The SQL standard includes an EXECUTE statement, but it is only for use in embedded SQL. This version of the EXECUTE statement also uses a somewhat different syntax. SEE ALSO
