Need a help here,

The USER_GETVAR needs a user_variable_name. I want to derive this user variable name from the argument that i pass to function, says ARGS(1,1). The argument ARGS(1,1) could be anything , velocity u, velocity v ,or velocity w, and, i need a gradient of the argument.

so, i want to generalize USER_GETVAR. Can anyone suggest what are the commands to convert the ARGS(1,1) into a character string. and how to convert this whole word into character fluid.ARGS(1,1).Gradient so, that i can pass,

user_variable_name = fluid.ARGS(1,1).Gradient into USER_GETVAR.

now, 'fluid name', i can get using GET_PHASE_FROM_VAR (CPVAR, CPHASE) , and
CALL CONVERT_NAME_S2U ('Phase',CPHASE,' ',User_Phase_Name,
& CRESLT, CZ,DZ,IZ,LZ,RZ) & User_Phase_Name(1:LENACT(User_Phase_Name)).ARGS(1, 1).
& // '.Gradient'

but, how do i convert ARGS(1,1) as a character string.

thanks for help and hints

regards
