FR L - Read (sets) a local symbolic parameter (string variable)

PURPOSE

Associates a file name template or any other string with a string variable (symbolic parameter). Reads input from current procedure or input stream. 'FR L' differs from 'FR' which receives input from the calling procedure or input stream.

SEE ALSO

FR	[Read (sets) a local symbolic parameter (string variable)]
FR F	[Read (sets) global symbolic parameter (string variable) from a file]
RR	[Read Register variables]

USAGE

.OPERATION: FR L

.PARAMETER LABEL & ASSOCIATED VALUE: [label]value
[Enter string's name (surrounded by []'s) and associated alphanumeric string.]

1. Example.

FR L
[raw_file]nerve{***[num]}

DO [num]=4,6
FS
[raw_file]
ENDDO

[num]=4
CP
[raw_file]
[raw_file]_jnk

When procedure executes, operation sequence is :

FS
nerve004
FS
nerve005
FS
nerve006

CP
nerve004
nerve004_jnk

NOTES

1. This operation is useful when writing long procedures as a string variable can be initialized to contain a certain value at the top of the procedure then the variable e.g. [raw_file] can be used throughout the procedure. If the string's value later changes then it only has to be altered at one location in the procedure.
