Passing parameters to 4GL file from shell script
Hi Please help me out for solving this problem. I want to execute a shell script and user will input a value for a variable. Let's say user will input the value "ABC". Then I want to call a 4GL file and pass the parameter "ABC" to the 4GL file. How we can achieve the same? Can we pass parameters to 4GL files in this way? Really appreciate your help. Thanks Nirmalya
Actually you can use arg_val parameters, for example: define g_user char(8) . . . let g_user = arg_val(1) So g_user variable content will be the first argument passed during the program call. If you desire more parameters, add them on the program call, separating with spaces, and add more variables on the program (arg_val(1), (2), and so on...) I hope this solves your question... Regards.

Try arg_val(n) where n is the location of the argument you are passing. This function will return the argument at location n -Michael On Fri, May 29, 2009 at 7:20 AM, NIRMALYA SINHA < nirmalyasinha@alcatel-lucent.com> wrote: > Hi > > Please help me out for solving this problem. > > I want to execute a shell script and user will input a value for a > variable. > Let's say user will input the value "ABC".

There are several ways to do this. See the Informix 4GL Reference manual for the ARG_VAL() and NUM_ARGS() functions to access commandline arguments. An alternative would be to export the environment variable and access it directly using the flg_getenv() function. Art Art S.
