SOLUTIONS for the Intermediate Tutorial (Tutorial 2).

These solutions are meant to provide a guideline as you work through the tutorial. However, there are often several ways to approach a programming challenge and solve each challenge. You may find that your solutions are different.

Exercise 1.1

The following code demonstrates this as the user chooses what kind of order will be processed:

00140  ! radio buttons
00150 let X$="Overnight"
00160 let Y$="Regular"
00170 print fields "12,5, c 30": "Shipping preference: "
00180 rinput fields "13,5,radio 9,2,8;14,5,radio 7,2,9":X$,Y$
00190 if FKEY=8, then print fields "15,5,c 30": "It will be there tomorrow!"
00200 if FKEY=9, then print fields "16,5,c 50": “It will be there with 3 to 7 business days!"
00220 if x$(1:1)="^" then shipping$="O"
00230 if y$(1:1)="^" then shipping$="R"

Exercise 1.2

The following code augments our sample program with the ability to select which items to ship:

00002 dim boxnameform$(3)*20,boxname$(3)*20,box$(3)*20
00004 data "22,15,c 10","23,15,c 10","24,15,c 10"
00005 data "Item 1","Item 2","Item 3"
00006 read mat boxnameform$
00007 read mat boxname$
00008 print fields "20,5,c 35": "Please select items to order:"
00009 print fields mat boxnameform$:mat boxname$
00010  !
00011 let X$="one" : let Y$="two"
00012 print fields "24,30,C 20": "Press Esc to quit"
00013 do
00014 input fields "22,14,CHECK 8,,10;23,14,CHECK 8,,11;24,14,CHECK 8,,12": box$(1),box$(2),box$(3)
00015 print fields "24,1,N 2": Fkey
00016 loop While Fkey~=99

In this example, the DO LOOP structure allows the user to choose more than one checkbox, while the Escape key allows the user to exit the program when complete.

Exercise 1.3 A

00260 dim Boxnameform$(3)*20,Boxname$(3)*20,Box$(3)*20
00270 data "22,15,c 10","23,15,c 10","24,15,c 10"
00280 data "Item 1","Item 2","Item 3"
00290 read Mat Boxnameform$
00300 read Mat Boxname$
00310 print fields "20,5,c 35": "Please select items to order:"
00320 print fields Mat Boxnameform$: Mat Boxname$
00340 print fields "23,30,CC 8,,b99" : "Done"
00350 do
00360 input fields "22,14,CHECK 8,,10;23,14,CHECK 8,,11;24,14,CHECK 8,,12": Box$(1),Box$(2),Box$(3)
00370 print fields "24,1,N 2": Fkey
00380 loop While Fkey~=99
00390 For I=1 to UDIM(box$)
00400 if box$(I)(1:1)="^" then ordered(I)=1 else ordered(I)=0
00410 next I

00008 print fields "12,5,c 40":"Enter menu number"

3.2 UPRCS

Answers may vary. One solution is to change the following line:

00470 let Lastname$(Newsize)=uprc$(Answers$(2))

3.3 LREC

Add a similar line to your program:

00655 print fields "21,30,n 4":lrec(1)

3.4 TIME$

Answers will vary. When writing the record, you will have to add TIME$ to the WRITE line and n 8 to the form line, also update the record length in the OPEN statement.

5.1 STR2MAT

Two different possibilities are shown below, for mat headings$ and mat forms$

Lines 30 to 70 of our example above could be replaced by the following:

str2mat("First Name,Last Name,Address,City,State,Zip Code,Shipping,Item 1,Item 2,Item 3", mat headings$,",")
data 10,10,10,10,4,9,3,3,3,3
read mat widths
f$="cc 30,cc 30,cc 30,cc 15,cc 2,cc 7,cc 1,n 1,n 1,n 1"
str2mat(f$,mat forms$,",")

5.2 SRCH

Note, your program might be different, but this is one successful option. With a short file, this task could be accomplished with FOR/NEXT and not SRCH, but in a very long list of clients, SRCH will speed it up considerably. The relevant code begins at line 380
