Hello Monks. Currently, I am making this program that pretty much serves as a study guide for my math class. Unit 6 has to do with quadrilaterals, so I made another script aside from Unit6.pl called CMQIA.pl that runs the "Casio-Maxim Quadrilateral Identification Algorithm" (don't ask). I made it so that if you type "quit" into the script, it'll go back to Unit6.pl. I used:  if($choice !~ /ready/i) {require "Unit6.pl";} Since require LABEL; runs the program, I thought it would work. However, since Unit6.pl has  if($Choice =~ /crazy maxim/i) {require "CMQIA.pl";} something really weird happens now. If I run Unit6.pl and I type crazy maxim, it goes to CMQIA.pl. Then, if I type quit in CMQIA.pl, it goes back to Unit6.pl. Then, if I go to CMQIA.pl from there again, it gives me:  Can't exec "Unit6.pl": No such file or directory at CMQIA.pl line 12, <STDIN> line 3. I've tried a bunch of other things in conjunction with the original code from CMQIA.pl, but nothing ever really works. Any solutions? This is the full code. Unit6.pl
#!/usr/bin/perl -w use strict; CHOICE: print " This is Unit 6 - Quadrilaterals and Polygons.\n For the Final Exam, you will have to know the\n properties of all quadrilaterals and how to\n prove that a given shape is any quadrilateral.\n To access the Quadrilateral Information Database,\n type 'Quads.' To access the Casio-Maxim Quadrilateral\n Identification Algorithm, type 'crazy Maxim.'\n Type 'quit' to exit Unit 6.\n Type your choice.\n\n"; my $Choice = <STDIN>; chomp $Choice; if($Choice =~ /quit/i) {print "\nBye.\n\n"; exit;} if($Choice =~ /quads/i) {require "Quadrilaterals.pl";} if($Choice =~ /crazy maxim/i) {require "CMQIA.pl";}
CMQIA.pl
#!/usr/bin/perl -w use strict; ORIGINAL: print " Welcome to the Casio-Maxim Quadrilateral Identification\n Algorithm. In order to identify said quadrilateral,\n you must have the coordinates of all 4 vertices.\n"; PROMPT: print " When you are ready to input your coordines, type\n 'ready.' Type anything else to exit the CMQIA.\n\n"; my $choice = <STDIN>; if($choice =~ /ready/i) {goto MAXIM;} if($choice !~ /ready/i) {require "Unit6.pl"; system("Unit6.pl"); requi +re "Unit6.pl"; goto ORIGINAL;} MAXIM: print "\nFor shape ABCD, in which point A has coordinates (X1, +Y1), B has coordinates\n\n(X2, Y2), C has coordinates (X3, Y3), and D + has coordinates (X4, Y4),\n\nX1 = "; my $AX = <STDIN>; chomp $AX; …

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
