"exists" function help

[tristanryerparke]

Hey all, I can't get the "exists" function working to check for a macro parameter. Since it was in the list of functions in the meta commands page I expect that it is used like so:

if exists(param.C) = true
	echo param.C
else
	M118 P0 S"No C parameter"

But the above script gives me this error:

Error: Failed to read code from macro grab_slotx.g: Failed to evaluate "exists(param.C) = true": expected an identifier

Am I doing this right? All the documentation I could find was that the "exists" function is now implemented.
Thanks,
T

@tristanryerparke
Try just

if exists(param.C)

	echo param.C

else

	M118 P0 S"No C parameter"

@owend tried cutting and pasting your code, still got the same error. Maybe its not avaliable on SBC yet?

@tristanryerparke which firmware version are you running?

[tristanryerparke]

@dc42 Sorry, should have mentioned in the original post, 3.3rc1 with DSF 3.3rc1.

@tristanryerparke there is a problem passing macro parameters from DSF to RRF in 3.3RC1. Try the RRF 3.3RC1+1 files at https://www.dropbox.com/sh/dlb58vkmu1u4fkx/AAAelkXSfRKVwI6_yqRnhGHPa?dl=0, or the RRF 3.3RC1+2 files at https://www.dropbox.com/sh/urr3rbnawf9ehcq/AAA_frdT0tcOXVlPUz3bHKU8a?dl=0.

I have tested an example similar to yours using the 3.3RC1+2 files in standalone mode. If you still can't get it working in SBC mode using these files then I will ask @chrishamm to take a look.
