Reading Data

[Katogoon]

Hello everyone,

I have been looking at Yabasic for a few hours today and it seems interesting, I have come across data in the manual and thought I'd give it ago. Here is what I have:

Code:

Label test
Read Name$, Age
Data "Katogoon", 19
Data "John", 25
Data "Smith", 63

As you can see I am storing names and ages. What I am trying to do is figure out how I can print Johns data on screen like so:

Code:

Name$ = "John"
Age = 25
Print Name$, " is ", Age, " years old."

Without the use of Variables though. (I think thats the correct term).

I don't know if understood what you was trying to do right, but anyway...

I would search through all the data (and add some sort of way to determine that you're at the end without counting all the data) and then report back whether the name was found or not. So something like this could be what you were looking for:

Code:

name$=""
age=0
target_name$="jake"

restore my_data

repeat
read name$,age
until( name$ = target_name$ or age < 0 )

if( age < 0 ) then
print "did not find ",target_name$
else
print name$, " is ", age, " years old."
fi

label my_data
data "john", 19
data "jim", 40
data "jake", 34
data "", -1

Hi Katogoon,

I don't think what you want is possible.

Information stored in DATA lines must be read into a variable first before it can be processed: A READ operation is the only way to access DATA information directly.

Or I misunderstood something...

Thank you both for your posts, I'm not sure if what I was asking for is possible to only print the information I wanted out of my data structure.

However the method Jacob posted there could work with what I wanted to do, as I can search for the required name and gather the information that way using the repeat loop.

Thanks a lot,
Katogoon.
