The GUI for my shell is developed but I got several questions for those of you with shell experience (or ice experience) regarding the mechanics of the shell.

1. How do you get the filename from a program using DetectVar. I know it would have to look somewhat like this:

Code:

Its the part after that is hard to figure out.

2. How do you run a detected program in a shell
3. How do you save scanned for pointers to filenames of detected vars.

Thanks!

Fistly, sum(20 returns the file name as a string, so just do sum(1 if an appvar, or sum(2 if other. Just use the returned string to open it.
Secondly, you can't run a detected prgm, but you can move its contents to another, predefined prgm and just run that instead.
Thirdly, use sum(4,STRING,legth(STRING),1,SLOT
Hope this helps
Also, useful types in fileIOC are:
5 prgm
6 protected prgm
7 temp prgm (I might be wrong on this one)
21 appvar

Ive tried opening this as a string, but I cannot figure out how to read the filename string.

1) USE SOURCECODER3!
2) It's said in the documentation, under Code Snippets
3) There is this code placed:

Code:

4) No, you can't run BASIC programs, which names is stored in a string.

exept you can run basic programs... If you have the name written directly in the code, if im not mistaken, just by putting the contents of the prgm you want to run into a predefined file.

Code:

Maybe Im slow but what is the code to read the filename. I know DetectVar provides a pointer to the filename, bu I dont know how I can read the data that this directs to. I have tried the GetTokenString command, Ive tried opening the pointer as a string. What exactly am I doing wrong?

The I would read it by:

Code:

Code:


Would this code work?
Also how can I tell how many "counts" the filename is before reading it to Str2?

length(PROG)

Code:

A few tips:
#1: variables in ICE are all numbers. To use more than three bytes (0 to 16777215, minimum and maximum numbers in ICE) in a variable, use strings,Data(),Alloc(),etc. This will return a number, which is used to get one, two, or three bytes from the data previously made. You can get the next bytes of the data by adding to the number returned by the creation of the variable.
#2: There is no structural differences between data types in ICE, aside from how they are read.

A few Routines:
String input routine (Call)
'I' is the input prompt
'R' is the default input, and the return variable

Code:


Number Input routine (Call)
'N' is the number to start with, and the return variable

Code:


If any of this doesn't work, please let me know, and I will fix it.
