Numeric

Arguments

cFieldName

Specifies the name of the field.

nWorkArea

Specifies the work area of the table for which FSIZE( ) returns a field size.

FSIZE( ) returns 0 if a table isn't open in the work area you specify.

cTableAlias

Specifies the alias of the table for which FSIZE( ) returns a field size.

Visual FoxPro generates an error message if you specify a table alias that doesn't exist.

cFileName

Specifies a file for which FSIZE( ) returns the size in bytes.

Remarks

The current setting of SET COMPATIBLE determines if FSIZE( ) returns the size of a field or a file. If SET COMPATIBLE is set to OFF or FOXPLUS (the default), FSIZE( ) returns the size of a field. If SET COMPATIBLE is set to ON or DB4, FSIZE( ) returns the size of a file.

The following table shows the default size (in bytes) for each fixed-length field type.

Field type Default field size(in bytes)
Currency 8
Date 8
DateTime 8
Double 8
Integer 4
Logical 1
Memo 4
General 4

The size of a field can be displayed with DISPLAY STRUCTURE and LIST STRUCTURE.

If you omit the optional nWorkArea and cTableAlias arguments, FSIZE( ) returns the field size for a field in the current table and work area.
