Slide 27 of 80
Notes:
- The CI does not support a direct mechanism to let the programmer know if a certain command, function, variable or other new feature is present on the system at hand. The bound() function lets you test for the existence of any variable prior to referencing it. It is trickier to test for the existence of a function prior to invoking it. Thus, it may be necessary to test the MPE OS version prior to using a new feature.
- :showvar @vers@ HPOSVERSION = C.70.00 HPRELVERSION = C.70.01 HPVERSION = X.70.11
- :vers On 7.0! :vers C.65.01 On 6.5!
