RESTORE
Changes the next read location for values stored with the Data statement.
Syntax:
Restore [label]
Description:
Sets the next-data-to-read pointer to the first element of the first Data statement after the label. The label must be contained in the same module as the currently-executing code. Restore alters the normal top to bottom order in which Data are Read. It allows re-reading some Data or using multiple sets of Data in a single module.
If label is omitted, the next-data-to-read pointer is set to the first Data statement found in the module.
If label is omitted, the next-data-to-read pointer is set to the first Data statement found in the module.
Examples:
' Create an 2 arrays of integers and a 2 strings to hold the data.
Dim h(4) As Integer
Dim h2(4) As Integer
Dim hs As String
Dim hs2 As String
Dim read_data1 As Integer
Dim read_data2 As Integer
' Set the data read to the label 'dat2:'
Restore dat2
' Set up to loop 5 times (for 5 numbers... check the data)
For read_data1 = 0 To 4
' Read in an integer.
Read h(read_data1)
' Display it.
Print "Bloc 1, number"; read_data1;" = "; h(read_data1)
Next
' Spacer.

' Read in a string.
Read hs
' Print it.
Print "Bloc 1 string = " + hs
' Spacers.
