Hi,
Would anyone let me know how ON condition works in VSCOBOL.
How do we convert a code using ON condition into a code that uses
IF condition.
Regards,
Sasi Patha.

hi,

here is the info i got about about ON condition .

its a part of "Converted COBOL Language Elements"...


The ON statement is not supported by the target languages.

The statement:
ON integer
imperative statement
is converted to:
ADD 1 TO LCP-ONCTR-nn
IF LCP-ONCTR-nn = integer
imperative statement
The statement:
ON integer-1 until integer-2
imperative statement
is converted to:
ADD 1 TO LCP-ONCTR-nn
IF LCP-ONCTR-nn > (integer-1 - 1) & < integer-2
imperative statement
A data item with the dataname LCP-ONCTR-nn (where nn is a sequence number) is added into the WORKING-STORAGE section with an initial value of zero.
More complex ON statements are flagged.

The most poular use of the ON stmt when it was supported was as a 1st time switch.

Very handy; I miss it.
