inputtrap...gosub statement

The inputtrap...gosub statement, using the str.exp, sets up an automatic computed gosub based on the next input @ statement data. The position of the character in the string expression corresponds to the position of the statement label in the list. This acts as a trap that causes a gosub on all subsequent input @ statements.

Syntax

inputtrap str.exp gosub statement.label{,statement.label...}

Parameter(s)


`str.exp`	An expression evaluating to characters to be searched for in the input.
`statement.label`	statement label to be branched to.

Description

Upon return from a gosub specification, execution continues at the statement following the inputtrap statement, not the input @ statement.

inputtrap must precede its associated input @ statement. Only one inputtrap statement can be active at any time.

Example(s)

inputtrap "abcd" gosub 10,20,30,40
input @(5,5):x
stop
10 print "You entered a"
return
20 print "You entered b"
return
30 print "You entered c"
return
40 print "You entered d"
return
