Problem with enabling user commands (in dyalogscript)

[justin2004]

in dyalog 19.0.50027

https://github.com/abrudz/aplcart/blob/master/table.tsv#L3711

e.g.

containeruser@2f67a68a70ab:/mnt$ cat script 
(⎕NS⍬).(_←enableSALT⊣⎕CY'salt')
⎕SE.UCMD'box on -trains=tree'
containeruser@2f67a68a70ab:/mnt$ dyalogscript script
VALUE ERROR: Undefined name: UCMD
 ⎕SE.UCMD'box on -trains=tree'
     ∧

this works however in RIDE.

It's not specifically an aplcart issue and I will also write to you from Support.

There is a setting DYALOG_INITSESSION which tells version 19.0 to initialise the session so that you get the Link and User commands:

Here is a Mac example of using dyalogscript:

#! /Applications/Dyalog-19.0.app/Contents/Resources/Dyalog/scriptbin/dyalogscript DYALOG_INITSESSION=1 DYALOG_CEF=0
⎕IO ← 0
⎕←'starting'
⎕←'.' ⎕wg 'aplversion'
⎕←2 ⎕nq '.' 'Getenvironment' 'DYALOG_INITSESSION'
⎕←'Found ⎕SE.Dyalog and Link:',⎕NC'⎕SE.Dyalog' '⎕SE.Link'
]box on -style=max -trains=tree -fns=on
⎕←⍳9
⎕←'done'

I just wanted to note this error here because this post references aplcart.

Also, this approach used to work in dyalogscript with Dyalog 18.2.x.
