This runs slowly

[Lance Edmonds]

Flex strings are still supported in the current version of PB/DOS.

FYI, UDT's are a *companion* feature, rather than a replacement for flex strings. The key differences between then is that flex strings can be dynamically created, resized and destroyed at runtime, whereas UDT's are have a fixed size that must be determined at compile time.

Therefore, if the data structures are "static" (that is, there size and format is not going to change at runtime), then UDT's can offer better runtime performance, because there is no runtime requirement to calculate data positions in memory, etc.

However, if the data format is changable, then flex strings provide an excellent and versatile way to manipulate data and sub-sets of data.

Flex strings are fixed-length strings that you can sub-divide into several smaller strings. They've been superceded by more versatile user-defined types in later versions of PB.

Look up the MAP statement on your PB documentation - it gets almost 5 pages in the PB 2.00 Reference Guide, and flex strings have a whole 2 pages in the Users Manual.

What are Flex Strings (the documentation I have only briefly
mentions them) and what are the advantages of using them??

Hi Martin,

Your code is very clear but...

1) use only Binary opened file -> speed
(may be You need some chr$(13,10) CR+LF after the text)

2) If You put$ or print #3 some text to the file put them
first together

yours:
print #3," B 0" '21 - 2nd of 2 pages
print #3," B *"

better:
crff$=chr$(13,10)
saven1$=" B 0"+crff$+" B *"
saven$ =" B 0"+crff$+" B *"+crff$
print #3,saven1$ --- in output modus
put$ #3,saven$ --- in binary modus

3) what is this ? ---- This needs lots of time

print #3," A ";left$(right$(ltrim$(str$(statements)),2),1)

amount1$ = ltrim$(rtrim$(mid$(idx$,4,14))) '6f

print #3," A ";right$(right$(rtrim$(str$(statements)),2),1) 'uses pages count in
---> right$(right$(...,2),1) is the same how right$(...,1)

there must be a simpler way to reach the same
is your data not formated ?
look for Flex Variables in Your PB-Book

You have a lot of work with Your "small" program.

I have a small program that runs rather slowly (a prexisting c/c++
program running the same data is roughly 10 times faster, although
this program is far simpler). Can anybody suggest ways to speed this
up?? btw, I'm using PB v2.1.
