Hi all,

 

Any idea why the following is only changing the size of the sg_gridToggle sg_lengthToggle arrays and not their values?

 

IF sg_noStoreyAbove > sg_noBasement then
			sizetokeep = min(vardim1(sg_customName), sg_noStoreyAbove)
		
			! copy existing values
			dim sg_lengthCustom_temp[][]
			dim sg_lengthCustom2_temp[][]
			dim sg_lengthToggle_temp[][]
			dim sg_gridToggle_temp[][]
			dim sg_gridToggle_display_temp[][]
			dim lp1_temp[][]

			dim lp2_v_temp[][]

You might want to add ;

sg_gridToggle = sg_gridToggle_temp

before ;

parameters sg_gridToggle = sg_gridToggle

You could try resetting the parameter values with an empty array e.g.

Dim arrNull2 [1] [1]

arrNull2 [1] [1] = "initial value"

oldarray = arrNull2

parameters oldarray = oldarray

 

I have situations where my parameter arrays wouldn't downsize and rebuilding from an empty array seemed to cure it.

@Palawat You might want to add ;

sg_gridToggle = sg_gridToggle_temp

That was done just a few lines above.

 

@DGSketcher You could try resetting the parameter values with an empty array e.g.

Isn't that what DIM sg_gridToggle_temp[ ][ ] does? Or is there something else I should be doing?

I started doing that in order to force the original dynamic parameter array to shrink before repopulating it with updated values. Maybe Parameter Arrays are processed differently to simple variable arrays. Sorry I'm not a GDL expert and my solutions usually come from trial & error.

Might it be related to:

During the interpretation, when a non-existing dynamic array element is given a value, the necessary quantity of memory
is allocated and the missing elements are all set to 0 (numerical).

Though only these two arrays are doing it...

Hm... I partially fixed it... I realised that since I had combined the up and down arrays [u][d] the values between the short and tall sides [u][u-x] were not getting set in the short side of the array [u-d]. This was an easy enough fix.

 

 

 

sg_lengthToggle_temp[i][1]			= sg_lengthToggle[i][1]
sg_gridToggle_temp[i][1]			= sg_gridToggle[i][1]
sg_gridToggle_display_temp[i][1]	= sg_gridToggle_display[i][1]
IF i > sg_noBasement then
		sg_gridToggle_temp[i][2]			= sg_Toggle_default
		sg_gridToggle_display_temp[i][2]	= "Show"
		sg_lengthToggle_temp[i][2]			= sg_Toggle_default
	else
		sg_gridToggle_temp[i][2]			= sg_gridToggle[i][2]
		sg_gridToggle_display_temp[i][2]	= sg_gridToggle_display[i][2]
		sg_lengthToggle_temp[i][2]			= sg_lengthToggle[i][2]
endIF

I was hoping my issue with increasing the overall array size would be solved in a similar way but this would seem to not be the case... So for [u][d], increasing d until it matches u, or viceversa, gives the correct default values, but increasing the max(u,d), still gives the incorrect return...
