HELP: External command (Subcommand) handler to update REXX parameters

Bernie Arruz #1 / 7	HELP: External command (Subcommand) handler to update REXX parameters How do I specify a REXX external command that is passed to my C subcommand handler and it updates certain parameters? Example Xaa = 0 Ybb = 0 Zcc = 0 NM_GET_XYZ {how do I pass Xaa Ybb Zcc so that) say Xaa Ybb Zcc will produce non zero values like 20 10 5 I would like to avoid function calls, but the C subcommand handler will test for the NM_GET_XYZ tag and when found it will be using variables Xaa,Ybb,Zcc and will assign values to them that will then need to be returned to REXX.

Bernie Arruz #2 / 7	HELP: External command (Subcommand) handler to update REXX parameters I would like it to work like PARSE [template], but since I'm new to REXX I have no clue about how to pass in a template to the NM_GET_XYZ command handler so that the Xaa, Ybb,Zcc variables are not evaluated (i.e. I dont want to pass in NM_GET_XYZ 0 0 0 to my C command processor). Thaanks for any help. Bernie.

Ian Colli #3 / 7	HELP: External command (Subcommand) handler to update REXX parameters Bernie Arruza entertained comp.lang.rexx with the following story: Quote: >How do I specify a REXX external command that is passed >to my C subcommand handler and it updates certain parameters? >Example >Xaa = 0 >Ybb = 0 >Zcc = 0 >NM_GET_XYZ {how do I pass Xaa Ybb Zcc so that) >say Xaa Ybb Zcc >will produce non zero values like 20 10 5 Make the syntax of your command something like "NM_GET_XYZ" "Xaa" "Ybb" "Zcc" (obviously this particular example could also be written as a single string "NM_GET_XYZ Xaa Ybb Zcc") so that you pass the names of the variables instead of their values. You will need to code the subcommand handler so that it collects the variable names from the command and then uses the Rexx Variable Pool Interface to set them to the desired values. -- ------ http://users.comlab.ox.ac.uk/ian.collier/imc.shtml New to this group?

Jerry Prath #4 / 7	HELP: External command (Subcommand) handler to update REXX parameters I'm currently trying to write a program to display timelines. My present approach is to use the slider object to select dates of interest. I thought the "detent" might be the very thing needed to allow the slider to snap to the various dates of significance scattered along the timeline. However, it appears that the slider will only snap to tick marks, not detents. I RTFM, but found no relief. Does anyone know of any "undocumented" technique to get the slider to snap to detents rather than ticks? Thanks, Jerry

Bernie Arruz #5 / 7	HELP: External command (Subcommand) handler to update REXX parameters Thanks Ian for: 1) reassuring me that it can be done 2) Pointing me in the direction of RexxVariablePool(...
