transfer parameters with sddsmakedataset

[Max]

Dear Michael and collaborators,

I am using the following instruction in a script:

sddsmakedataset settings.sdds -parameter=EARTHFIELDc,type=double,units=T -data=0.00005 -parameter=DV1c,type=double -data=-0.015 -parameter=DV2c,type=double -data=0.015 -parameter=NKICKSc,type=double -data=0

so that I can input certain parameters without having to redefine them every time in the .ele files as follows:

&alter_elements
name = DR*
type = STRAY
item = LBY
string_value = EARTHFIELDc
&end

&alter_elements
name = ACCT*
type=rfcw
item=N_KICKS
string_value=NKICKSc
&end

and this works after downloading settings.sdds with &rpn_load.

The parameters DV1c and DV2c I use in:

&error_element
name=ACCT0_L00.02
item=VOLT
type="plus_or_minus"
amplitude=DV1c
fractional=1
&end

and this does not work (DV1c is not recognized), presumably because there in no instruction like "string_amplitude". Is there a way I can make "amplitude" read the parameter DV1c in settings.sdds ?

Thanks, Max

Michael and collaborators,
a correction. Not even the instructions:

&alter_elements
name = DR*
type = STRAY
item = LBY
string_value = EARTHFIELDc
&end

&alter_elements
name = ACCT*
type=rfcw
item=N_KICKS
string_value=NKICKSc
&end

really work (I was fooled by the fact that there was no error displayed, but the value is not transferred). Perhaps to use rpn_load in the fashion I want (alter elements) is not allowed ?
I remember in a previous query you advised me on the use of rpn_load on the instruction "insert_elements", but that instruction does not seem to work with "alter_elements".

Thanks from an obviously very confused

Max,

On the &alter_elements commands, try

value="(EARTHFIELDc)"

etc. This is how you access values from the RPN subsystem in namelist entries.

If that doesn't fix it, please upload the entire .ele file (or mail it to me).

It works.
Thanks a lot Michael.

Cheers, Max
