Re: IBM mainframe 360/30 vs. iPad 2019

I remember making a large stress analisys program (Finite Element Method) in Fortran IV on the new IBM 360/30 mainframe in the late sixties.

Good plan for ongoing upgrading. 8-)

… Any draw and fill settings (including color, alpha, dash, and shadow) must be set before calling one of the functions, just like normal DRAW and FILL commands.

You do not have to be a fool to forget that :P

Re: "Quick & dirty" file selector

Thanks Henko,
My own solution to find and select files is far too complex for easy use. viewtopic.php?f=20&t=1530&p=9321
This solution is very elegant and useful in most cases. :!:

Re: PDF manual 5-8

The manual has been updated with a note on function definition with string as returnvalue on page 15

Example:

Code: Select all

DEF spaces$(n) ' return string with n spaces
a$=""
FOR i=1 TO n
  a$&=" "
NEXT i
RETURN a$
END DEF
