I remember there being a couple of programs for my 28s called PRG-> and ->PRG. They functioned as follows: on the stack: 4: 3: 2: 1: << RCL DUP PURGE >> (or whatever) PRG-> executed would give: 6: << 5: RCL 4: DUP 3: PURGE 2: >> 1: 5 (this all being accomplished through the use of sysevals) ->PRG would take the stack in part 2 and give you what you started with. After all, we can get all of the symbols (<<, >>, RCL, etc.) onto the stack with sysevals. Is there a way to implement the same programs on the 48sx? If someone could post their solution, it would be muchly appreciated. Thanks in advance, Rob -- _______________________________________________________________ |Rob Prior - President, Still Animation Logo Design, Burnaby, BC| |---------------------------------------------------------------| | Mail to: a634@mindlink.uucp | | ___ _ or: !uunet!van-bc!rsoft!mindlink!a634 | | /__ /_\ "You must find us.... a shrubbery!!!!!!" | |____/ / \____________________________________________________|

Do you mind if I ask what good this is? Aside from that, something similar can be accomplished by either creating the program as a LIST or converting the program to a list and then using OBJ-> to decompose to the stack. The result is the same with the exception that the program delimiters are not among the commands and functions on the stack. ->LIST will recompose the object and EVAL will run it as a program. ``Give it a whirl sometime, Doctor.''

The problem with using a list as the program is that it won't automatically be evaluated when you press the key corresponding to a variable in which it is stored. A while ago I wanted to write a little program which would automagically cons up a program (which simply called another one with a particular set of args) and store it in a handy variable. But I couldn't figure out how to do this... -Miles
