Images in dropdowns

$valrep(field) = “val1=^img1·!Rep 1 ·; val2=^img2·!Rep 2“

^glyph - glyphs need to be compiled into UOBJ.

@filename - images loaded from a fileserver .

#fieldname - images loaded from a BLOB field in database.

&url - images from the web (only works in server pages).

Undocumented - assignment files

• It is now possible to list all of the logicals at once, like this...{אפשרויות נוספות==\}list = $assignments("LOGICALS") \("FILES") \ ("DRIVER_SETTINGS") ver 9

• $print_assignments Print assignments in the transcript window ver 9

• $assignment is what uniface assembles from a couple of ASN Files

• (like usys.asn etc.)And if you have identical lines, the new ones will replace the older ones.So sometimes you may be surprised when lines are listed which you can not find in "your" ASN file. Or lines do not have the values as you see it in the ASN file.Especially (because it works on a first fit) is when you use file redirections with wildcards.

Performance of list processing

destructive list

while ( list != "" )

count = count+1

getitem temp,list,1

delitem list,1

Endwhile

never do a destructive list poor performance

delitem is causing the whole list to be rebuilt - very costly

getitem with a reverse destructive list

getitem temp,list,-1

delitem list,-1

much better performance

Validating a numeric string

use a syntax string to pattern match for numbers...

if ( $length(str) = 8 & str = '#*' )

;

endif

improve this even further...

if ( str = '########' )

; much better

endif

Assignment operators

Addition: c += 1 (which is the same as c = c + 1)

Subtraction: c -= 1 (which is the same as c = c - 1)

Multiplication: c *= 1 (which is the same as c = c * 1)

Division: c /= 1 (which is the same as c = c / 1)

Modulus: c %= 1 (which is the same as c = c % 1)
