2 000A0002 R__ 8512 C:\DATA2.DAT

3 000C0003 R__ 8512 C:\DATA3.DAT

4 001E0001 R__ 0 C:\DATA4.DA

3 The table returns the open file handles in hexadecimal. To convert a handle

to one that other

xpctarget.fs methods, such as fclose, can use, use

the

hex2dec function. For ex ample,

h1 = hex2dec('001E0001'))

h1 =
