OPENFILE(NAME, MODE)
ARGUMENT TYPE DESCRIPTION
name cstring The file to be opened.
mode int The mode in which the file is to be opened…
0 = Read Only
1 = Read/Write at Start of File
2 = Read/Write at End of File
DESCRIPTION
Returns a handle to the file name located on the CompactFlash card. This function is restricted
to a maximum of four open files at any given time. The CompactFlash card cannot be
unmounted while a file is open. Note that the filing system used on the card does not support
long filenames, and that if backslashes are included in the pathname to separate path
elements, they must be doubled-up per Crimson’s rules for string constants as described in the
chapter on Writing Expressions. To avoid this complication, forward slashes can be used in
place of backslashes without the need for such doubling. Note also that this function will not
create a file that does not exist. To do this, call CreateFile() before calling this function.
FUNCTION TYPE
This function is active.
RETURN TYPE
int.
EXAMPLE
hFile := OpenFile(“/LOGS/LOG1/01010101.csv”, 0)
