hello everyone,

I want a pass a argument which is optional in function. Can it be done in LN?

function tfgld.date conv.utc.to.date.num(
domain tcpono i.x,
[ref domain tcpono i.y])

{

if get.argc() = 2 then
message( " two args %d - %s " , i.x , get.long.arg (2) )

else
message( " 1 args %d " , i.x )
endif


}

Thank you, Vamsi Gujjula

Got the solution

Hi Vamsi Gujjula,

I was looking for this solution, thanx for the solution,

Now one problem is there, when I am passing values to optional argument, I didn't get that value to the functions. so what to do?

Hi,

Is the variable you are passing declared extern?

Hi,

I m passing table fields values as argument.

Hi,

Try declaring your table as extern. Also if that doesnt work try assogning table field value to a variable.

Now one problem is there, when I am passing values to optional argument, I didn't get that value to the functions. so what to do?

Refer to the following functions to get the values from the optional arguments.

get.double.arg(), get.long.arg(), get.string.arg() (http://www.baanboard.com/programmers_manual_baanerp_help_functions_varying_arguments_get_many_arg)

Functions with variable number of arguments: sample program (http://www.baanboard.com/programmers_manual_baanerp_help_functions_varying_arguments_example)

Sample code:

function extern void show.file( const string fname(),
[string devc(14)])
{
...
if get.argc() = 2 then
devc = get.string.arg(2)
mode = 0
if tt.device(devc, dev.desc, devtype) then
splid = spool.open("", devc, 0)
else
splid = spool.open("", "", 1)
endif
else
splid = spool.open("", devc, 1)
endif
...
}

hmmm NPRao... took on my post..... :p ..just kidding..

Thank You NPRao
