Video posted about the TI-74 BASICALC Pocket Computer - Steve Simpkin - 07-17-2022 05:09 AM There is a great overview of the TI-74 BASICALC Pocket Computer that was just posted over on the Calculator Culture YouTube channel. Antony also has a lot of other excellent videos about programmable/business calculators and pocket computers on his channel including a number of HP models.

Well my TI-74 (ser.no. 9193619) does return values in scalar variables, i.e. they are passed by reference. If you want to use "by value" put the variable in parentheses in the call statement.

Brian, Good catch! I think the following pages from the TI-74 Programming Reference Guide explain the process you describe. [attachment=10882] |
