Summary
The GETPOSITIONEDIT procedure returns the record number (1000 times the EDIT

returns the current record number).
GETPOSITIONEDIT is an IOEdit procedure and can only be used with files that have
been opened by OPENEDIT or OPENEDIT_.
Syntax for C Programmers
•
CEXTDECS (via the included file TNSINTH) defines 32-bit values as the typedef
__int32_t which for TNS and TNS/R compiles is defined as
long and for TNS/E
compiles is defined as
int.
Syntax for TAL Programmers
Parameters

INT(32)
returns the current record number (1000 times the EDIT line number) of the

beginning. It returns -2 if the last operation was a read end-of-file.
filenum input
