Re: Call a external program from a program

I have run into this problem before. I never understood the reason,

compilation is "KRAFT" OBJ\->

The OBJ\-> or STR\-> command, with a string as its argument,
in fact "compiles" the string at that late time,
while you are running whatever program contains those commands.

So if by that time 'KRAFT' is a variable in the current or higher directory,
then that variable will be evaluated; otherwise if KRAFT is a command
in an attached library, that library command will be performed.
If neither, then 'KRAFT' will still be left on the stack.

Performing object-time compilation every time is slower than just editing
the calling program once, however, so unless you are specially providing for
calling something which metamorphoses back and forth between
being stored in a variable vs. in a library,
it may pay to just edit the calling program once,
after the called program or command has been installed,
which is sufficiently late enough.
