Warning, premature end of input , use <Shift> + <Enter> to avoid this message.
Error, unterminated loop
Error, unterminated for loop
Description
Examples
To enter multiline inputs without generating warnings, press the Shift+Enter keys. This produces another line in the same input region.
Example 1: With 1-D Math input, the warning message premature end of input occurs.
for i from 1 to 5 do f(i)
Warning, premature end of input, use <Shift> + <Enter> to avoid this message.
Solution: Use the Shift+Enter keys.
for i from 1 to 5 do f(i) end do;
f1
f2
f3
f4
f5
Example 2: With 2-D Math input, the error message unterminated loop occurs.
for i from 1 to 5 do fi
for i from 1 to 5 dofiend do;
Example 3
Sometimes you may see this error if you inadvertently hit Enter before you finish the input. This example is missing the right parenthesis:
sin(Pi
To fix the problem, simply complete the input expression. Here, the matching parenthesis needs to be added:
sinπ
0
