Problem Statement

A pangram is a sentence that contains all the letters of the English alphabet at least once. For example:   The quick brown fox jumps over the lazy dog.

Write a function or method to check a sentence to see if it is a   pangram   (or not)   and show its use.

Let's start with the solution:

10 I=1
20 :I)=0
30 I=I+1
40 #=26>I*20
50 ?="Enter sentence: ";
60 C=$
70 #=C=13*120
80 C=C<97*32+C-96
90 #=C>27*60
100 :C)=1
110 #=60
120 ?=""
130 I=1
140 N=0
150 N=N+:I)
160 I=I+1
170 #=26>I*150
180 #=N=26*200
190 ?="not ";
200 ?="a pangram"
