Eof Function

Vraća da li je pokazivač u datoteci dosegao kraj datoteke.

Syntax:


Eof (intexpression As Integer)

Return value:

Bool

Parameters:

Intexpression: Any integer expression that evaluates to the number of an open file.

Koristite EOF da izbjegnete greske kada pokusate citati iza zavrsetka datoteke. Kada koristite Input ili Get izraz za citanje iz datoteke, pokazivac na datoteku se pomice za roj procitanih bajtova. Kada se dođe do kraja datoteke, EOF vraća vrijednost "True" (-1)

Error codes:

5 Invalid procedure call

52 Invalid file name or file number
