TitleReader's Clinic - Slow Multivalued Screen Display
KeywordsMULTIVALUE
SCREEN
XLATE
DISPLAY
TextMartin Northey of the Inland Revenue recently queried why certain screens
took so long to display up to 40 seconds in some cases! The delay was
tracked down to the existence of several ASSOCIATED multivalues
incorporating XLATEs to another file The symbolic being used was

@ANS = xlate(FILE KEYS FIELD ACTION)<0 @MV>

where KEYS was a multivalued key list The purpose of the <0 @MV> was to
prevent a problem whereby if the display area was not filled by MULTIVALUES
previous values would repeat to fill up the display area

It was found that if the above formula were written as

@ANS = xlate(FILE KEYS<0 @MV> FIELD ACTION)

the screen refreshed 10 times more quickly as only the MULTIVALUES actually
required were calculated!
