Zone stamp 2d script, Need Help Please, Thanks.

Anonymous — Fri, 20 May 2005 00:36:47 GMT

Hi,
This my first attempt write GDL. I have tried to modify the Zone_Stamp_02.gsm to show the Occupant load Factor (set as integer) and an Occupant Load ((set as integer) of an area. In 2D script I am getting some sort of mismatch errors in two places but can not fix them after 5 hrs of trial! could any one guide me? (attach is the file)

!!!room_perim = "P: " + room_perim + lin_unit
room_perim = peritext + room_perim + lin_unit

!!!ol_factor = "OL Factor: " + ol_factor
ol_factor = olftext + ol_factor < HAVING PROBLEM WITH THIS LINE

code_string=basec!!!!+" "+wallc+" "+ceilc

set style "znamestyle"
w_roona = (stw (Zname)) * name !*** width of the strings - 0 if not displayed

set style "znumstyle"
w_roonu = (stw (ROOM_NUMBER)+2) * num

set style "codestyle"
w_code = (stw (code_string)+2) * code

set style "arstyle"
w_rooar = (stw (room_area)+2) * area

set style "pestyle"
w_peri = (stw (room_perim)+2) * peri

set style "chstyle"
w_roohe = (stw (room_height)+2) * ceil_s

set style "olffstyle"
w_olf = (stw (ol_factor)+2) * olf < HAVING PROBLEM WITH THIS LINE

max_len = max (name*w_roona, num*w_roonu, peri*w_peri, area*w_rooar, ceil_s*w_roohe, code*w_code, olf*w_olf) !*** width of the stamp
max_detlen = max (num*w_roonu, peri*w_peri, area*w_rooar, ceil_s*w_roohe, code*w_code, olf*w_olf)
max_h = - name*shight - (num + floor + area + peri + ceil_s + code + olf) * shight2 !*** height of the stamp

In the first problem line, you are trying to add two values which are not the same kind. 'olftext' is a string (textual) value, and 'ol_factor' is an integer (numeric) value. The + operator in GDL is designed to only add things of the same kind, e.g. '1 + 1 = 2' or '"ABC" + "DEF" = "ABCDEF"'. The problem line says something like '1 + "ABC" = ???'

You can convert a number to a string with the STR function. So your line could be changed to:

ol_factor = olftext + STR(ol_factor, 8, 0)

Read the documentation on STR to determine how you can best use it. The script now works with this change, but I would recommend another related change. The variable called 'ol_factor' is a parameter with an integer value. In your script you subsequently assign a string value to it. Although this works, I recommend not changing a variable's type. Create a new variable instead:

olFactorText = olftext + STR(ol_factor, 8, 0)
...
w_olf = (STW(olFactorText) + 2) * olf
...
TEXT2 dist, -vlen, olFactorText

Thanks a million Jay,
Two more questions:

1. Based on what you say, In expression "w_olf = (STW(olFactorText) + 2) * olf" what is the reason for multiplying by "olf" parameter? Is it that if this parameter olf, is 1 if set to ON and 0 if set to OFF so we want to make the value of "w_olf " to zero when olf is set to OFF so will not have effect on other parts of the script?

Futher more, If so 1 or 0 are INTEGERS and olFactorText is TEXT?

2. Also based on what you say, the previous line of the code on ROOM_PERIM = PERITEXT + ROOM_PERIM + LIN_UNIT should not wok either since: ROOM_PERIM is lengthand I assume a REAL number and PERITEXT is text!?
Thanks,
Joseph

The STW function returns the (display) length of a string, i.e. it's size when it is displayed in a drawing. Therefore, STW(olFactorText) will give you the length of the string in the variable olFactorText.

The parameter olf is a boolean variable - it can only have two values or states which you could describe as true or false, on or off, 1 or 0. If you use a boolean value in an arithmetic expression, it will have the value 1 if it is set to true, or 0 if it is set to false.

This particular line will result in a length of 0 if 'olf' is false because it will be multiplied by 0. Otherwise, it will return the length of 'olFactorText + 2'.

No, all the variables in that line are text. The author of the script has assigned text values to variables that were originally numbers:

room_perim = str (lin_form , ROOM_PERIM)

The confusion you are feeling is the reason for my suggestion to use different names rather than changing the type of an existing variable.

Thanks and have a GREAT week end, after your guidance I will have a great one also.

Ralph,
I tried to get the integer (INT) portion of the parameter room_area so I can have the area with out the decimals (for better representation in the stamp), but I am getting an error.
I guess it is because it is converted to text somehow. Could you give me guidance how to convert it back to integer AND/OR not showing the decimals?
Thanks very much,
Joseph

Yes, it is converted on the following line:

room_area = str (area_form, Temp_CalcArea)

It would be better to use a different variable name for the text version so you can retain the original value (and the two can't be confused with each other), e.g.

roomAreaText = str (area_form, Temp_CalcArea)

The author of this object has used lower case for the text variable, so you could quickly change every instance with "Find & Replace..." provided you check the 'Case Sensitive' option.

Welcome Back and here I go again,
I took your advice and changed all the
room_areas TO roomAreaText

A. This is how it looks:

IF ROOM_POLY_STATUS=0 then Temp_CalcArea=ROOM_CALC_AREA !! Method 1 and 2
IF ROOM_POLY_STATUS=1 then Temp_CalcArea=ROOM_CALC_AREA !! Method 3/Net
IF ROOM_POLY_STATUS=2 then Temp_CalcArea=ROOM_AREA !! Method 3/Gross

Temp_CalcAreaINT = INT (Temp_CalcArea) !!!!!<<<<<TO GET THE INTEGER

area_form="" !*** format as set in the Preferences
rrr=request ("Area_dimension","",area_form)
!! roomAreaText = str (area_form, Temp_CalcArea)
roomAreaText = str (area_form, Temp_CalcArea)

But to my surprise from the variable Temp_CalcAreaINT not only I do not get an integer but a value of ZERO?!

B. Then tried using from the "cook book" string=STR(item,6,1) gives you ‘123.5’ and applied it to:
roomAreaText = str (area_form, Temp_CalcArea,0) so I at lease get the area to show with out decimals I get an error?

C. On top of it all what is the variable area_form?

I have got a big headache with this, I hope I have not given it to you.
Thanks,
Joseph
