Answer / malathy

A field symbol is a pointer you can dynamically assign to a
field. after assignment you can use the field symbol
anywhere in your program in place of the actual field name.
Use the field symbol statement to define the field symbol
and use assign to assign a field to it.field symbols name
must begin and end with an angle bracket.
Here is an example program.

Data : f1(3) value 'ACD'.
field-symbols <f>.
Assign f1 to <f>.
write <f>.
<f> = 'ghh'.
write f1.

Answer / guest

Field symbol does not phsically reserve a space for a
field,but it points to the field which is not known untill
the run time of the program.It's closely related to pointer
conept in C.
