If you can't find the methods Vitaliy mentioned because (for example) your Cache version is too old, you can always reinvent the wheel and write your own encoder/decoder method. Where is the problem? This snippet could be a starting point

Parameter Base64 = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";

ClassMethod Base64Enc(x)
{
    s f=-$l(x)#3, x=x_$e($c(0,0),1,f), y=..#Base64, z="" zt:$ziswide(x) "WIDE"
    f i=1:3:$l(x) s a=$a(x,i)*256+$a(x,i+1)*256+$a(x,i+2), c=262144 f j=1:1:4 s z=z_$e(y,a\c+1), a=a#c, c=c\64
    s:f z=$e(z,1,$l(z)-f)_$e("==",1,f) q z
}

Some comments...

(1) you can generate a string with the necessary commas, (2) also, the variable "l" is unnecessary and (3) after assigning to "m" the length of the first word, start the for-loop with the next (second) word...

According to problem description, the string will never be empty, so an early "q 0" is also not necessary and for the case, this happens, the first piece of the string will have a length of 0.

Parameter WhiteSpace = {$C(9,10,13,32,160)};

ClassMethod Short(t) As %Integer
{
  s t=$zstrip($TR(t,..#WhiteSpace,$tr($j("",$l(..#WhiteSpace))," ",",")),"<=>",",")
  s m=$L($P(t,","))
  f i=2:1:$L(t,",") {s n=$L($P(t,",",i)) s:n<m m=n}
  q m
}

In case, the shortest word is longer then  200 chars, than the result will be wrong. Instead of using a constant (200)

  s l=$L(t,","),m=200
  f i=1:1:l {s n=$L($P(t,",",i)) s:((n>0)&&(n<m)) m=n}

use a more generic approach

  s l=$L(t,","),m=$L($P(t,","))
  f i=2:1:l {s n=$L($P(t,",",i)) s:((n>0)&&(n<m)) m=n}

Also, removing the unnecessary delimiters (commas) simplifies the code too

ClassMethod Short(t) As %Integer
{
  s t=$zstrip($TR(t,$C(9,10,13,32,160),",,,,,"),"<=>",",")
  s m=$L($P(t,","))
  f i=2:1:$l(t,",") {s n=$L($P(t,",",i)) s:n<m m=n}
  q m
}

A small change (two bytes longer) to your solution makes it perfect, I think, for all cases

ClassMethod findShort(s) As %Integer
{
 f i=1:1 ret:$locate(" "_s_" "," [^ ]{"_i_"} ") i
}

BUT, and that's, what I want to say: this function is an awesome demonstration of economic nature of ObjectScript in comparison to Java. Your one-liner vs. a whole page of code... I love ObjectScript!

Sorry, that had to be said...

First of all, it's meaningless to post several KB of raw data. Either provide it somewhere for download or make an attachment (if possible).

Second, Base64 encodings converts 3 (incoming) bytes into 4 (outgoing) bytes, this means you always (except the last one) have to read multiple of 3 bytes at once, convert it, and put into the output stream. Your file.Read() reads 32000 bytes, which is NOT a multiple of 3!

Don't ask me,how accurate they are...

I have an (some ten years old) one which I use in the %ZSTART routine. Sometimes (for maintenance or whatever other reasons) you have to (re)start Cache and nowdays IRIS, but you want to start just some of the automatic processes listed in %ZSTART. If you forgot to disable those other before shutdown a init-file comes handy to disable things before start. A sample section looks like this:

[Start]
# 0 = do not start
# 1 = start
LoginServer = 1
UserLogin = 0
SystemTasks = 1
UserTasks = 0

I added some more comments to the class, you can download the InitFile.xml (class export) from my FTP server (which will be open for the next few days).

The general syntax for calling routines from another namespace is:

do label^|namesapce|routine

where

- you can omit the label and

- namespace is either the name of the namespace (like set namesapce="USER") or the path to the database (preceded by two carets), where the routine resides.

I see right now, Config.MapGlobals accesses the ^SYS global via the path to the database (take a look at the Storage section) - so in theory, you  can  call all classmethods from the above class as:

do zClassmethodname^|"%SYS"|Config.MapGlobals.1(args...)

merely, I do NOT recommend to do this (the cass is in deployed mode, so we do not know, what the code really does and (instance)methods are private, so you can't call them from outside).

Julius Kavay · Jun 28, 2022

First, the correct (or better) way for the above code snipet were:

new $NAMESPACE
zn "%SYS"
do ##class(Config.MapGlobals).Delete(...)
quit

second, one can call routines (and (class)methodes are compiled to rotines) from another namespace by using extended syntax, but in that case such a routine uses the globals (if the routine does a global access) from the CALLING namespace. In Your case this won't work because the Config.MapGlobals uses globals which resides in %SYS namespace and not in the namesspace you are in.
