A function can be used almost anywhere. For instance if you wanted to print
numeric date just use the function with date enclosed in ():
Like:
PRINT NUMDATE(TODAY)
Most functions will give you format and use. Probably my two most common
functions are NUMDATE and SETDATA. Then you can make your own.
SETDATA(FIELD1,FIELD2) sets FIELD1=FIELD2 OR SETDATA(FIELD1,FIELD2+12) and
almost any expression you desire can be executed. Functions made me the lazy
programmer I am today. Most users think of functions in a print statement.
However, they can be used in triggers and almost any place you can specify a
field. ...tx/t
NAME: NUMDATE//
MUMPS CODE: S:X X=$E(X,4,5)_"/"_$E(X,6,7)_"/"_$E(X,2,3)
Replace
EXPLANATION: DATE IN 'NN/NN/NN' FORMAT//
DATE-VALUED:
NUMBER OF ARGUMENTS:
WORD-PROCESSING:
NAME: SETDATA//
MUMPS CODE: S X1=X//
EXPLANATION: SETS FIRST ARGUMENT EQUAL TO THE SECOND ARGUMENT
Replace
DATE-VALUED:
NUMBER OF ARGUMENTS: 2//
WORD-PROCESSING:
