BASIC CODE: FUNCTION
Example of the FUNCTION and DEFFUN commands versus the SUBROUTINE and CALL commands.
Code Example
---File this as a program called DOZ.CONVERT:
function DOZ.CONVERT(NMBR, DIRECTION)
if DIRECTION = 'TO.DOZ' then RESULT = NMBR/12 else RESULT = NMBR * 12
return(RESULT)
---File this as a program called DOZ.SBR:
subroutine DOZ.CONVERT(NMBR, DIRECTION)
if DIRECTION = 'TO.DOZ' then NMBR = NMBR/12 else NMBR = NMBR * 12
return
---File this as a program called TEST.DC:
DEFFUN DOZ.CONVERT(VALUE,DIR)
CRT DOZ.CONVERT(12,'TO.DOZ')
CRT DOZ.CONVERT(12,'TO.UNITS')
*
QTY = 12
CALL DOZ.SBR(QTY,'TO.DOZ')
CRT QTY
CALL DOZ.SBR(QTY,'TO.UNITS')
CRT QTY
CALL DOZ.SBR(QTY,'TO.UNITS')
CRT QTY
STOP
---
The results will be an output of 1,144,144,12,1.
