FileManage (Manage Files)
The FileManage instruction is used to manage files from within a running datalogger program.
Syntax
FileManage ( "Device: FileName", Attribute )
Example
The following program uses FileManage to run TC-TEMP.cr300, which is stored on the datalogger CPU, after 120 scans of the program.
Public PTemp, TCTemp
BeginProg
'Run Program 120 scans
Scan (1,Sec,3,120)
TCDiff (TCTemp,1,mv34,1,TypeT,PTemp,True,0,4000,1.0,0)
NextScan
'Branch to second program
Scan (1,Sec,3,0)
FileManage ("CPU:TCTemp.cr300",4)
NextScan
EndProg
Remarks
FileManage is an instruction that allows the active datalogger program to manipulate program files that are stored in the datalogger.
Parameters
"Device:FileName" (Device and File Name)
"Device:FileName" is the device and name of the program file that will be executed (RunProgram) or manipulated (FileManage). The Device on which the file is stored must be specified and the entire string must be enclosed in quotation marks.
Type: Variable string
Attribute
A numeric code to determine what should happen to the file affected by the FileManage instruction. Attribute codes are a bit field. The codes are as follows:
| 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/Run on powerup |
| bit 3 | 8 | Delete |
| bit 4 | 16 | Delete all |
| bit 5 | 32 | Hide |
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.
Type: Constant
The Restart instruction can be used to restart a datalogger program under program control, rather than using FileManage to Run Now/Run On Powerup.
