| Parameter | Type | Description | |

Description
The command
PA_GetVirtualFieldNumber
returns the virtual table and field numbers of a true field. These are the numbers in the virtual structure mode.
Pass the true table number in
trueTable
, the true field number in
trueField
, and, if no error occurs, retrieve the virtual numbers in the short pointed by
virtualTable
and
virtualField
.
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.
