[Gretl-devel] function execution in 'if' statement

Hi, this is a point I don't understand and frequently stumble over. Function main() calls checker(). When checker() is called first, it correctly prints the message "Some error message" and correctly returns 1. When checker() is called within the conditional-statement,  <if checker(1)>, it also returns correctly 1 which triggers printing the message "Check returned some other error". However, printing the checker's message "Some error message" 'fails' or is not done. Why is this the case? <hansl> function scalar checker (scalar code)     if code         print "Some error message"         return 1     endif     return 0 end function function void main(void)     scalar ret = checker(1)     if ret         print "Check returned some error"         # print-command in checker() properly shown     endif     # checker(1) evaluated and correctly returns '1'     # However, print-command in checker() not shown     if checker(1)         print "Check returned some other error"     endif end function main() </hansl> Thanks, Artur
