"do build.sh cosmos.asm" looked for a file called "build.sh cosmos.asm", because scriptOpen copied the whole rest of the line into the name. So a script could be told nothing, and a launcher - a script whose entire job is to hand on what it was told - could not exist. Now the name is cut off the front and what follows is kept whole. $1 to $9 are the words of it, walked out on demand, and $args is all of them. Nothing is stored per parameter, so there is no limit on how many a script may be handed and no second number to keep in step. Both ways of starting a script pass them on: "do" and typing the name. A word that was not given is an error that stops the script, like every other name this shell does not know. Expanding it to nothing would let a command run with an argument missing and then report success, which is what stop-on-failure exists to prevent. $args is always set inside a script, empty if it was given nothing, so "if same $args" can be asked. ---- And the count that describes the block was already wrong ---- Found while adding a field to it. The state one script keeps for another is saved by a single copy of a fixed number of bytes, and that number was 71 against a block of 77: six bytes of line position had been added in the middle of it years after the count was written. So the tail of every saved script was never saved, and #quiet in a helper stayed behind in the script that called it - the opposite of what this file's own comment promises and the README documents. The unsaved line position turned out not to matter, because a loop keeps its own copy in the block record. Nothing said so. Three numbers describe this block and all three now say so in a comment, and cosmosScriptNest ends on a helper that goes quiet and a caller that must not stay that way.
