---|
79 | CATEGORY: |
---|

---|
81 | CALLING SEQUENCE: |
---|
82 | new = str_token( old, token ) |
---|
83 | INPUTS: |
---|
84 | old -- String to be split. Contains text after in, out |
---|
85 | token on output. |
---|
86 | token -- Token to use in splitting old. in |
---|
87 | KEYWORD PARAMETERS: |
---|

---|
89 | before returning. |
---|
90 | /HELP -- print useful message and exit. |
---|
91 | OUTPUTS: |
---|
92 | new -- portion of string up to token. out |
---|
93 | old -- portion of old after token. out, in |
---|
94 | COMMON BLOCKS: |
---|
95 | SIDE EFFECTS: |
---|
96 | Input parameter old is modified. |
---|
97 | NOTES: |
---|
98 | Token may be one or more characters. |
---|
99 | If token is not found, returns old and sets old to ''. |
---|
100 | EXAMPLE: |
---|
101 | If old is 'foo44 bar', then str_token( old, '44' ) would return |
---|
102 | 'foo', and upon return, old will be left with ' bar'. If /TRIM |
---|
103 | were set, old would be 'bar' on return. |
---|
104 | |
---|
105 | If old='xyz', then new=str_token(old,'a') would return with |
---|
106 | new='xyz' and old=''. |
---|
107 | THANKS: |
---|
108 | To D. Linder who wrote GETTOK, part of the goddard library, |
---|
109 | upon which this is based. |
