**xcall SIZE, fspec, count \{,flags\}**

SIZE returns the size of the specified file in bytes.

**Parameters**

_fspec_  ([String](string.md))  \[in\]

is specification of the file (in DevPPN or native format).

_count_  (Signed [Num](num.md))  \[out\]

returns the number of bytes. If the file does not exist, -1 is returned. A return value of 0 indicates that the file exists but contains no data.

_flags_  ([Num](num.md))  \[in\]

specifies what to return in the _count_ parameter:

| **Value** | **Data Returned** |
|------|------|
| 0 (default) | Number of bytes in file |
| 1 | Number of lines in (text) file |
| 2 | Number of non-blank lines in (text) file |




**History**

2015 December, A-Shell 6.3.1501:  Add _flags_. Prior to this update, the routine only returned the number of bytes in the file, as if _flags_=0.

2015 January, A-Shell 6.1.1400:  Routine now supports files larger than 2GB when the returned parameter is any F type. Previously, it only avoided the 2GB limit for F,6.
