option to omit the C wrapper

[GitMensch]

RE e315799

You've noted in your video that you couldn't figure out how to omit the C wrapper.
Doesn't the following work?

77 SDL-RWops-Pointer  usage pointer.

           call 'SDL_RWFromConstMem' using
               by reference ground-asset-data
               by value ground-asset-data-size
               returning SDL-RWops-Pointer
           end-call
           call 'IMG_LoadTexture_RW' using
               by value renderer SDL-RWops-Pointer 1
               returning ground-texture
           end-call

Note: obviously it is quite longer so a wrapper makes sense in any case - the nearest you'd get to that in COBOL would be writing a user-defined-function; the result would be a wrapper invoked as:

           move function loadTextureData (ground-asset-data, renderer)
               to ground-texture

To pass variable lengths you'd use 01 texture-data pic x any length. for the data on the function's LINKAGE, then pass by value function length (texture-data) in the CALL.

Thanks for the info! I'll try to look into it soon.
