The next example show the use of Wend.
While X > Y

The following is equivalent to the prior While/Wend construct with easier to
follow context:
Do While X > Y
'Much better

FileManage
The FileManage instruction is used to manage files from within a running
datalogger program.
Syntax
FileManage( "Device: FileName", Attribute )
Remarks
FileManage is a function that allows the active datalogger program to
manipulate program files that are stored in the datalogger.
Parameter
& Data Type Enter FILEMANAGE PARAMETERS
Device;
Filename
Text The "Device:Filename" argument is the file that should be manipulated.
The Device on which the file is stored must be specified and the entire string
must be enclosed in quotation marks. Device = CPU, the file is stored in
datalogger memory. Device = CRD, the file is stored on a PCMCIA card..
Attribute
Constant The Attribute is a numeric code to set what will happen to the file affected
by the FileManage instruction. The Attribute codes are actually a bit field.
The codes are as follows: Setting a file's attributes to Hide makes it
inaccessible using communications or the keyboard, but it can still be set as
Run Now or Run on Power Up..
Bit Decimal Description
bit 0 1 Program not active
bit 1 2 Run on power up
bit 2 4 Run now
bits 1 & 2 6 Run now and on power up
bit 3 8 Delete
bit 4 16 Delete all
bit 5 32 Hide
FileManage Example
The statement below uses FileManage to run TEMPS.C9X, which is stored on
the datalogger's CPU, when Flag(2) becomes high. The currently running
program will be stopped and TEMPS.C9X will start running.
If Flag(2) then FileManage ( "CPU:TEMPS.C9X" 4 ) '4 means Run Now
