Need some help with unknown function!

Hello all,

I am reviewing a .c program that runs as a batch process for Oracle. I am not quite sure how to interpret the following line of code:

input(in_term," Term :",6,ALPHA);

or

input(one_up_no,"Enter Parameter Sequence Number: ",26,NUM
Questions:

1. Where do I find information on input()? Is this a built in function, I have tried to create a test.c program to see how it works and I get a compiler error, unknow.

--> I can figure it is displaying a prompt and receiving user input, but what is ALPHA and NUM? and why can't I use input in a separate program.

Thank you for any help in advance

it will be a function in some library your program is using.
NUM and ALPHA (if I were to write this) would be integer constants, NUM meaning "numeric" and ALPHA meaning "alphanumeric".

The second parameter could be the number of positions that the input is allowed to be, though a 26 long numeric field seems excessive.

If you figure out what library the function is in and what preconditions there are to using it you should be able to use it.

Yeah that's the thing, I couldn't find the library that its in,

I finally found the library file, thanks for ure help.
