Parse

[Hamilton, Robert L]

Here's a parse opportunity for some one:

<code>

/* main REXX program */

str = 'a_b-term=2004F'

parse var str 1 'term=' value

if value > '' then say value; else say 'no value';

exit 0

</code

What i need is value only if 'term=' starts in column 1; if term=
is found after col 1 then ignore it. . .

REXX returns value = 2004F; Is there a way to parse from col 1 only? I
need to ignore term= if it starts after

col1

If I'm understanding your below statement correctly,

"What i need is value only if 'term=' starts in column 1; if term=
is found after col 1 then ignore it. . ."

With this as your example text string
str = 'a_b-term=2004F'

Try this;
If Left(Str,5) = 'term=' Then Parse Var Str 'term=' Value .

[Doug Lee]

Try the following:

str = 'a_b-term=2004F'
If pos('term=',str) = '1' Then Do

parse var str 1 'term=' value
if value > '' then say value; else say 'no value';

End

William & doug; looks like either will be the way but I was hoping to
get PARSE to start in column 1, without the extra code.

Thnx

Try this then

Parse Var Str 1 str1 6 Value
If Str1 \= 'term=' Then <do what you do to ignore this>

How about:

str = 'a_b-term=2004F'
parse var str junk 'term=' value
if junk == '' and value > '' then say value; else say 'no value';

If you wish to permit leading blanks in the string preceding
the 'term=', then change the double == to a single = above.

IF LEFT(str, 5) = "term=" THEN value = SUBSTR(str, 6)
