| Syntax |
INPUTTRAP string.expression GOTO statement.label{ ,statement.label{,...}}
INPUTTRAP OFF |
| Category | BASIC |
| Type | Statement |
| Description |
using the string.expression, it sets up an automatic "computed goto" based on the next input @ statement's data. The position of each character in the string.expression corresponds to the position of the statement.label in the list. This acts as a "trap" which causes a "goto" on all subsequent "input @" statements and branches to a label in the current program.
"inputtrap" must precede its associated "input @" statement. Only one inputtrap statement can be active at any time. If data is entered that does not correspond to the inputtrap string.expression then no "trap" occurs and execution continues with the statement after the "input @". "inputtrap off" cancels any previous "inputtrap" statement. |
