Flags
Flags are a useful program-control tool. While any variable of any data type can
be used as a flag, using Boolean variables, especially variables named "Flag",
works best. CRBasic example Flag Declaration and Use
(p. 121)
shows an example
using flags to change the word in string variables.
CRBasic Example 10. Flag Declaration and Use
Public Flag(2) As Boolean
Public FlagReport(2) As String
BeginProg
Scan (1,Sec,0,0)
If Flag(1) = True Then
FlagReport(1) = "High"
Else
FlagReport(1) = "Low"
EndIf
If Flag(2) = True Then
FlagReport(2) = "High"
Else
FlagReport(2) = "Low"
EndIf
NextScan
EndProg
