Purpose

FLD is used in field logic and causes processing to continue at a specified destination field.  There are two versions of the FLD command one for Screen functions and one for reports.
 

Syntax

When used in Screen logic

FLD (field){,skip{,backtab}}…)


When used in Report logic

FLD (field,{option})
 

Operation

When used in Screen logic

field is the destination field number or the Tag Name of the field.  If less than 1 FLD is treated as a null operation.  If it is greater than the number of fields in the function it is treated as though the last field of the function has been processed.

Skip is any valid numeric constant variable or expression.  Non-zero indicates skipped fields of a cycle are to be displayed.  Zero indicates skipped fields are not to be 'displayed.  

Backtab is any valid numeric constant variable or expression.  The value tells the system how to respond if a back tab is entered in the destination field of an cycle.  Non-zero means return the cursor to the first input field prior to the first skipped field.  Zero means return the cursor to the first input field prior to the destination field.


When used in Report logic:

field is the destination field number (1-255) or the Tag Name of the field.  If less than 1 FLD is treated as a null operation.  If it is greater than the number of fields in the function it is treated as though the last field of the function has been processed.

Option = 0 (default) to process any line feeds associated with this field, or #0 to skip any line feed processing associated with this field.
 

Remarks

Fields are normally processed sequentially.  FLD is used to skip fields in the current cycle or to alter the standard processing flow.   

No Logic is executed for the fields skipped.

A field number is local to the function in which it is defined; so field 1 in function CUST and field 1 in function INV are separate entities.  It is not possible to skip from a field in one function to a field in another function.

When FLD is executed, the remaining statements within a logic routine are processed before control is passed to the specified field number.  If multiple field statements are executed within a logic routine, control is passed to the field number specified in the last FLD statement executed.

In Screen functions, the FLD statement causes PROIV to jump to the specified field in the current cycle.

In Report functions, the FLD statement causes a jump to the specified field in the current cycle.  The field containing FLD in its Field logic is printed in the report but skipped fields are not.
