Description
The MLINE() function extracts a line of text from the specified <memofield>. The <expN> specifies the line number in the range 1 to MEMLINES(). The length of the line extracted is set by the command SET MEMOWIDTH.
Example
use prospect set memowidth to 40 m_last = memlines(comp_hist) for n=1 to m_last m_line = mline(comp_hist,n) ? m_line next
