Sometimes a field from a Child Segment has multiple lines of free text. Let's assume the length of the Child Field is 40 but you would like it to be reformatted to print a length of 30. The following example converts the text stored in the Child Segment into another table called /GMOD but with a length of 30 instead of 40. Then the contents of /GMOD are put into an MV Array:
""^TEMP, DO{>/GMOD[TEMP]^TEMP ""^/GMOD[TEMP]}, %NUR.TOOL.BOX.convert.length(^@Root(@child.segment),^/GMOD,30), ""^TEMP, DO{+(/GMOD[TEMP],LN)^TEMP " "_LN^@Z.rpt.mv[MARKER,TEMP,FIELD]}
MARKER would need to be replaced with whatever value used in your MV Line Attribute. FIELD would be replaced by the field # on your Report Picture.
