Title: MACROS SizeStr and SIZESTR
Post by: jj2007 on May 18, 2008, 04:45:54 PM

I have a macro with a number of arguments, of local and global variables.

Global:

Arg1	equ a234567890
Arg2	equ a234567890
glob$	equ a234567890

Call:

Code Select

MyMac Arg1, Arg2

The macro:

Code Select

MyMac MACRO arg1:REQ, arg2:REQ
  LOCAL loc$, tc$, tmpnu
  loc$ equ <1234567890>
  echo.
  echo Test with SizeStr
  tc$ CATSTR <Size of glob >, %@SizeStr(glob$)
% echo tc$
  tc$ CATSTR <Size of loc >, %@SizeStr(loc$)
% echo tc$
  tc$ CATSTR <Size of arg1 >, %@SizeStr(arg1)
% echo tc$
  tc$ CATSTR <Size of arg2 >, %@SizeStr(arg2)
% echo tc$

  echo.
  echo Test with temporary number and @SizeStr
  tmpnu=@SizeStr(glob$)
  tc$ CATSTR <Size of glob >, %tmpnu
% echo tc$

  tmpnu=@SizeStr(loc$)
  tc$ CATSTR <Size of loc >, %tmpnu
% echo tc$

  tmpnu=@SizeStr(arg1)
  tc$ CATSTR <Size of arg1 >, %tmpnu
% echo tc$

  tmpnu=@SizeStr(arg2)
  tc$ CATSTR <Size of arg2 >, %tmpnu
% echo tc$

  echo.
  echo Test with temporary number and SIZESTR
  tmpnu SIZESTR glob$
  tc$ CATSTR <Size of glob >, %tmpnu
% echo tc$

  tmpnu SIZESTR loc$
  tc$ CATSTR <Size of loc >, %tmpnu
% echo tc$

  tmpnu SIZESTR arg1
  tc$ CATSTR <Size of arg1 >, %tmpnu
% echo tc$

  tmpnu SIZESTR arg2
  tc$ CATSTR <Size of arg2 >, %tmpnu
% echo tc$
ENDM

Here are the results. Expected value is in all cases 10 characters, so only the last version works...

Code Select

Test with SizeStr
Size of glob 5
Size of loc 6
Size of a234567890 4
Size of a234567890 4
.
Test with temporary number and @SizeStr
Size of glob 5
Size of loc 6
Size of a234567890 4
Size of a234567890 4
.
Test with temporary number and SIZESTR
Size of glob 10
Size of loc 10
Size of a234567890 10
Size of a234567890 10

Question: Where is my newbie error in this...?

Usually I don't help noobies, but ...

the evaluation operator % must be placed before the expression which is to be evaluated

tc$ CATSTR <Size of glob >, @SizeStr(%glob$)

if it is placed before @SizeStr(), it converts the numeric value returned by @SizeStr to a literal (05 -> 5)

You have a good heart, Japheth - it is very touching that you made an exception in my (hopeless) case :U
