Ok - there is a bug in GDL manual
"REQUEST ("ASSOCLP_PARVALUE", expr, name_or_index,type, flags, dim1, dim2, values)"
- noone noticed that expr - which is for parameters name should be written in quotation marks "expr".
I have found the working example in "object marker" or "object label" so I am rewriting the "WD marker" object to read out the fire and acoustic rating - the key was:
re_fire=REQUEST ("ASSOCLP_PARVALUE", "gs_list_firerating", nameind_fr, type_fr, flag_fr, dim1_fr, dim2_fr, val_fr)
re_acou=REQUEST ("ASSOCLP_PARVALUE", "gs_list_acousticrating", nameind_ar, type_ar, flag_ar, dim1_ar, dim2_ar, val_ar)
val_fr is the value of the parameter "gs_list_firerating" in asociated door / window
