[Sticky] INDEX: list of Proclaim Maths functions

[steve]

one use is for comparison operators
e.g.

Code: Select all

IF 1 NOT= 1 THEN 
    MESSAGE( "not eq" )  
ELSE 
    MESSAGE( "eq" ) 
END 

this 'compiles' when syntax checked to

Code: Select all

IF 1 <> 1 THEN 
    MESSAGE( "not eq" )  
ELSE 
    MESSAGE( "eq" ) 
END 

likewise there are 'translations' for
NOT=,!=,LE,GE,LT,GT

Hi Steve,

I was expecting it was going to be more unique.

Thanks again

returns a character string from a list, based on an integer position

LISTITEM (list , element , character)

example

Code: Select all

vlist = "Monday,tuesday,wednesday,thursday,friday,saturday,sunday"
v1 = listitem(vlist,1,","{
message ("first day is ",v1)
#prints Monday

CAVEAT/BUG
If you use a field for defining your starting list, then do not use the comma delimiter as it doesn't work.

Code: Select all

#set up example alpha field with comma delimited text
put( "Monday,tuesday,wednesday,thursday,friday,saturday,sunday", {mytext field.Alpha})
#retrieve field into variable
vlist = TEXT( {mytext field.Alpha})
v1 = listitem(vlist,1,",")
#or v1 = listitem({mytext field.Alpha},1,",") - doesn't work either
vcount =listsize(vlist,",")
message ("Count: ",vcount) #returns 1!
message ("first day is ",v1) #errors: prints Monday,tuesday,wednesday,thursday,friday,saturday,sunday

Any examples of using a list to store integers instead of strings?
