Hi Everyone!

I have a question about the PRINT(); command.

I don't know why my program is skiping the PRINT(); command...

I have the following code:

EXPORT test()

BEGIN

LOCAL me;OP;

me:="To find the shortest distance between a point and a line, you need to provide one of the following data sets:

1) Ax+By+C=0 & P(x₀,y₀)

2) y=mx+b & P(x₀,y₀)

3) P1(x₁,y₁),P2(x₂,y₂) & P(x₀,y₀).";

PRINT();

PRINT(me);

CHOOSE(OP,"I Have...",{"Ax+By+C=0 & (x₀,y₀)","y=mx+b & P(x₀,y₀)","P1(x₁,y₁),P2(x₂,y₂) & P(x₀,y₀)"});

END;

when I run this code, it jumps right straight to the CHOOSE command, and I never get to see the text.

Any ideas about what could I be doing wrong! I'll appreciate it.

CHOOSE operates on a different graphics buffer than PRINT, if I'm not mistaken. Does it still behave this way if you place a WAIT(-1) in between the PRINT and CHOOSE ?

The LOCAL declaration needs a comma separator:

LOCAL me, OP;

Otherwise a wait(-1); for the terminal screen to display me:

Code:

EXPORT test()

PRINT();

PRINT(me);

wait(-1);

CHOOSE(OP,"I Have...",{"Ax+By+C=0 & (x₀,y₀)","y=mx+b & P(x₀,y₀)","P1(x₁,y₁),P2(x₂,y₂) & P(x₀,y₀)"});

yes, in fact.

I was writing the same thing

it should be the comma...
