CRBasic Example 60. Formatting Strings
'This program example demonstrates the formatting of string variables. To run the
'demonstration, send this program to the CR1000. String formatting will occur
'automatically.
'Objective:
'Extract "12.4 Volts" from the string "The battery is 12.4 Volts"
Public StringVar As String
BeginProg
'Note line continuation character _
StringVar() = Mid("The battery is 12.4 Volts", _
InStr(1,"The battery is 12.4 Volts"," is ",2)+3,Len("The battery is 12.4 Volts"))
EndProg
