FieldPosSym Function

Return the position of a field that is identified by a symbol.

Namespace: XSharp.RT
Assembly: XSharp.RT (in XSharp.RT.dll) Version: 2.19

Syntax

Copy

 FUNCTION FieldPosSym(
	sFieldName AS SYMBOL
) AS DWORD

public static uint FieldPosSym(
	Symbol sFieldName
)

Request Example View Source

Parameters

sFieldName: Type: Symbol
A symbol that corresponds to the name of the field.

Return Value

Type: DWord
The position of the specified field within the list of fields associated with the work area.
If the work area has no field with the specified name, FieldPosSym() returns 0.

Remarks

FieldPosSym() is the inverse of the FieldName() function. FieldPosSym() is most often used with the FieldPut() and FieldGet() functions. By default, this function operates on the currently selected work area.
It can be made to operate on an unselected work area by specifying it within an aliased expression

Examples

This example demonstrates a typical specification of the FieldPosSym() function:

Copy

1USE customer NEW
2QOut(FieldPosSym(#Name))                // Result: 1
3QOut(FieldGet(FieldPosSym(#NAME)))            // Result: Kate

This example uses FieldPosSym() to return the position of a specified field in a unselected work area:

Copy

1USE customer NEW
2USE invoices NEW
3QOut(Customer->FieldPosSym(#Name))            // Result: 1
4QOut(Customer->FieldGet(FieldPosSym(#Name)))    // Result: Kate
