| Parameter | Type | Description | |

Description
The command
PA_GetTrueFieldNumber
returns the true table and field numbers of a virtual field. Those are the numbers in the real structure, the one that is defined in the design environment.
Pass the virtual table number in
virtualTable
, the virtual field number in
virtualField
, and, if no error occurred, retrieve the true numbers in the short pointed by
trueTable
and
trueField
.
If you want to call API routines that use table/fields numbers, be sure to switch between virtual/real structure if necessary, depending of what you want to do.
The virtual structure is used when the 4D commands
SET TABLE TITLES
and
SET FIELD TITLES
are called.
