Api QP0FPTOS passing parameters

Hi all

I'm try to use QP0FPTOS api to check if an Ifs obj is locked and who Lock
it;

running CALL PGM(QP0FPTOS) PARM((*LSTOBJREF) ('/Mypath/MyFile')
(*FORMAT2)) works fine



if i run this

DCL VAR(&MYPATH) TYPE(*CHAR) LEN(70)

chgvar VAR(&MYPATH) VALUE('/Mypath/MyFile')

CALL PGM(QP0FPTOS) PARM((*LSTOBJREF) (&MYPATH) (*FORMAT2))



I receive CPE3025 This path or directory does not exist



Where am i wrong ?



Thanks in advance
