Text Length Command
The Text Length command designates the number of lines (at a given
VMI) within the logical page available for printing text, the text area.
This effectively defines the bottom margin.
? & l # F
# = Number of lines
Default = 1/2 inch less than maximum text length1
Range = Logical page length minus top margin
1 Maximum text length = INT(logical page length - top margin). However, if the max
text length is less than ½inch, the text length is set to the maximum allowable.
The value field (#) sets the text length in lines referenced from the top
margin. If a value greater than the logical page length minus the top
margin is specified or if the current VMI is 0, the command is ignored.
The user default text length is invoked whenever the orientation, page

length is computed as follows:
Note The user default VMI is selectable using the control panel; VMI is
calculated from the FORM menu setting.
